Last these day I have been proving new writeups of amination. Always I have used nitrometane as source of metylamine, with good succes  but not perfect results as for yields.
 Some time ago I did a few hundreds of grams of metylamine following the bright star´s method that never used. That is to say, with  only 1 filtering of the residual ammonium chloride and without doing any type of purification with chloroform or recrystallization.
I am going to prove the variant of reduction with methylamine, methanol,.... proposed by Roundbottom: " Osmium/BrightStar Al/Hg Methylamine Reductive Amination ", posted on Rhodium,since the yields are really interesting, and the process is way more simply and easier than  Methyl's man method. I am going to use a scale 10X minor to try with few amounts of ket.
My question is with regard to the quality of the produced methylamine following the bright star´s method:i know that is not pure, something  about 95 %, and it must contain significant quantities of ammonium chloride and other amines.. But the production of mda as a side product would not be a  problem. Only wish that  yields were not lowering in excess due to this lack of purity of the methyilamine.10-20% less hydrocloride would not be a problem to handle.It´s posible to need to add some extra mg. of this methylamine to  assure a propper amount of it?
 Some experience using methylamine done with this process?

Proved that methylamine(without cleaning) and worked fine.Roundbottom write-up of the reductive amination with methylamine/AL/HG/MeOH rocks!!both about lower solvents needed,easy procedure  and good yields!Seems too that the product it´s a little more trippier about effect. i have never obtained the expected yields from Methyls´man method ,but of course i supposed my problem wastoo  on crystallization with gas.Anyway,this write-up works way easy.
    Only one thing.The methylamine gas smell .It´s way stronger than produced Using nitromethaneas methylamine source,using exact the same equipment and conditions(cold water with a reflux condenser):Methyalmine gas come over easy.Maybe will try a better and longer reflux condenser.i Really hate that smell that fix on the room for days.Anyway,the product and yields were the expected .
   Only maked diferrent the crystalization to try another method than gas and worked fine.Extract the amine from the final toulene with 10 %HCL and let evaporate water at room Temo:Takes days,but works fine!
   I recommend this write-up as the first to try if it´s your first AL/Hg.Of course  at this day is easier get nitromethane than make Metylamine,but it´s really hard to go wrong.

Osmium/BrightStar Al/Hg Methylamine Reductive Amination

http://www.erowid.org/archive/rhodium/chemistry/redamin.os-bs.html

wow, Jon.  the OrgSyn procedure was always my reference but it definitely gives incomplete conversion of the NH4Cl (and slow workup on a small funnel).  i didn't know it was possible to get a close-to-complete conversion without having problems with dimethylation.  VL mentioned slight vacuum, he specified 20 inches of Hg, which confused some people (who tried 20 mmHg and failed) and is still much higher than what you're talking about.

i disagree that pure MeNH2.HCl is not so hygroscopic though.  i had relatively pure MeNH2.HCl from the OrgSyn procedure and it turns into a puddle after a couple hours of air exposure.  NH4Cl in contrast is much less hygroscopic.  did you try to recrystallize the methylamine hydrochloride from alcohol to see it's purity?  i understand of course even a good bit of residual NH4Cl should not interfere at all in the next reaction.

beer bottles, heh.  we made some hydroxylamine in champagne bottles- similar concept.

i remember the OrgSyn procedure being tedious.  alcohol is added and distilled off to remove water.  nh4cl is cropped off once.  the next two crops give MeNH2.HCl contaminated with nh4cl.  the MeNH2.HCl is extracted from the nh4cl with boiling dry isopropanol then precip'ed.

i was wondering quantitatively how much the use of vacuum improves yields and decrease the amount of residual nh4cl.  i guess it doesn't matter though any improvement is worth a try, after which all will become clear.

ummm with vacum i cropped no ammonium chloride just like the refs say, temperature is also key that's why the salt water baths you can't fuck it up this way.
it's qauntitative try it and see.
and salat, i enjoy reading your posts i think you're smarter than you let on.

dcm and tce also rid the dimethlamine.
that's why i recommend salt water baths (saturated salt water) they hold tempertures at 106 and you never overshoot temps..
beats watching a thermometer.

i don't see why not but he's just going to have to reduce it under vacum again mine as well rinse it in the bushner funnel.
next time tell him to use ethanol.

Yeah, yeah - I messed-up the Brightstar MeAm synth!  I've been playing with "the classic" synth to better understand it, and didn't keep my eye on the ball (so to speak).  SO... LARGE flask, SMALL single neck, LOTS of VERY hard product adhering to flask bottom and keeping both my spinbar and thermocouple tube HOSTAGE!  ON THE BOTTOM no less! 

<sigh>  that's what I git for not warming a beaker for over 7 years... but life's good now - VERY good

Anyhow - I FINALLY logged on to say something other than the intro.  Oh, yeah - if anyone wants to know, I've had a great deal of successes - I know a LOT of things that DON'T work!

Bee-was

Got it covered, Jon... just got the gallon of n-Butyl alcohol I've been waiting for.... just the THANG for cleaning it up without needing to mess about (in an EXTREMELY humid place!) making absolute EtOh - more like OH!  Anywho... I'm not exactly trying to get to a "destination" - as I sed, I'm trying to understand the reaction dynamics.  Clearly, one wants to move the puppy "to the right", i.e. eliminate the formic acid, which is the immediate product that's clogging the reaction pipe (given that this is an equilibrium deal).  Mother nature to the rescue!  It spontaneously (under the right conditions!) decomposes into CO2 (how nice!).  THAT can be hurried up with some vac (as wuz mentioned earlier in the thread).  Oh, BTW - in the Brightstar writeup, they "figger" you'll have about 3-4% NH4CL and perhaps as much di-MeAm, which for all intents and purposes one "shouldn't notice" were one to (HORRORS!) actually commit an illegal act.  My trials seem to agree, tho I didn't do the quantitative analysis to confirm (if that answers the original posts' question).

The OTHER way I thought of getting rid of the formic was to add MeOH, which would POOF! make a VERY LOW BP Methyl formate.  Uh... didn't pan out very well.  Now, since I got myself into a bind with the last tests, I'm fiddle-forting about with off-the-wall ideas once the stuff had (allegedly) finished reacting.  I say "allegedly" because I DID get a small crop of NH4CL, so I either had too much to start with, or I screwed the pooch along the way.  I'm also displeases with the near-orange color of the final brew - this I suspect was from the loooonnngg ramp-up time to get to 104c (about 4 hours to get there, then 5 hours AT 104, give or take 0.2c).  Temp control I've GOT DOWN - just playing with the reaction to REALLY understand it.

Hope that answers all those burning questions no one's asked yet

just buzzing 'round

Just requested two papers on the acid/thermal decomposition of urotropine/hexamine. I've done the reaction, but I'd dearly love to know if there is a way to add excess ammonium salts to stop the formaldehyde/formic acid production. That shit stinks the place down.

Ok the references are in (Java is a wonder), hydrolysis of hexamine with acetic acid gives acetamide and formaldehyde, two VERY FUCKING USEFUL chemicals which are a bitch to acquire easily. I'll throw up the paper on the Hoffman Degradation of Acetamide to give methylamine as well (given that acetamide is easily made via hexamine). Any input on how to rapidly form paraformaldehyde from the formaldehyde generated by the reaction?

PS Another paper on the production of methylamine from ammonium chloride and 40% formalin solution, it is attached.

PPS Has anyone got a selective preparation of dimethylamine? Right at the moment alkaline hydrolysis of various weed-n-feed-type products (present as about 500g/L in several combinations) as the dimethylamine salts seems like the best "selective" route... I want it to try out the dimethylchloramine + phosphine = RP + dimethylammonium chloride reaction, but dimethylamine:borane looks tasty too.

Just to be safe you could always put a drying tube over your flask/vessel

Whats your definition of high yeilding? Trying to get MeCl from that method is not that simple or high yeilding and to top that off as the ammonia concentration goes down it starts to form Di and Tri methylamines meaning that atlest a 10-20x molar concentration of Amine must be kept at all times to ensure alternative products from your 5-20% yeild of Chloromethane from the first part of the synthesis.

Sorry But I have seen this proposed many times and I doubt it can be pulled off with any usefullness. Im positive there are simpler ways.

Same thing... I get chloromethane in high yields (MeCl being taken off the solution the equilibrium goes to the right...) and then again high yields of MeNH2. I'd say it contains around 5% DiMeNH2 but can be easily purified with solvent extraction

Coin care to do a writeup with pictures and a melting point test if you are able. I have seen many others suggest otherwise on MeCl being anything but high yeilding (<30%)and thats even with a catalyst like Zinc Chloride avalible.

The following is an alteration of Eleusis' variant of the ethanol method. Into a 2:1 molar ratio mixture of formlin:NH4Cl in a suitable open vessel is added ethanol dropwise or in portions under stirring at room temperature or slightly warmed, until the rumlike odor of ethyl formate can no longer be detected. Then, the mixture is heated to drive off water and worked up as per usual.

As Eleusis and Android have demonstrated, that isn't necessarily the case. See this writeup:

Methylamine Hydrochloride from HMTA, Eleusis' version [with comments by Rhodium]{with SWIM's comments in white)

140g of Hexamine is carefully dissolved in 400mL of Muriatic Acid(swimming pool) (31.45% HCl) to which at least 100mL of (preferably) absolute ethanol(SWIM used denatured) has been added. Add the hexamine slowly while stirring vigorously and with good ventilation as some nasty fumes are produced. Allow all to stir at room temperature for at least 8 hours but preferably 16(SWIM would leave it under the overhead stirrer for 16hrs). The solution will become turbid within several hours of the initial mixing. I *believe* this is the formation of a formaldehyde(ammonium chloride) trimer of some sort and I suspect that the original equation for the conversion of hexamine into methylamine fragments is therefore incorrect. [There is no trimer of any sort formed, if enough water and formaldehyde is present. Eleusis uses 4 moles of amine to 6 methylenes, which is enough, but gives less yield.] At any rate, filter off this white precipitate which is obviously not an amine salt due to it being fluffy even in Florida's humidity (almost all simple amine salts are hygroscopic) [With the exception of ammonium chloride, and this is it]. Finally, remove the excess water, hydrochloric acid and freako volatile products by, ideally, heating the liquid at low to medium heat in a porcelain saucepan(Visionware pot). Stove-proof glass would be ideal, but stainless-steel, aluminum and copper are definitely not! [Rather use a RB flask, with a water aspirator attached, smells considerably less]. The concentration can generally be left unattended for a couple of hours, but try to stick around and babysit it at least the first time so you will have a good idea of how long it takes for your particular stove/pots/etc... [Or else it'll BURN!] Also, the methylamine HCl will form a melt if heated too long at which point it will sublimate off. It will then appear as if it's taking forever for the stuff to concentrate when in fact you are merely boiling your product away. After the concentrated slush has become sufficiently "thick", take it off the heat every so often to see if it doesn't soldify, insuring that the water is mostly gone and that not too much sublimation has occured (some is inevitable and even desireable). The yield of Methylamine HCl should be around 200g as white deliquescent crystals(beautiful, closer to 100g after all is said and done). Note, ACS-grade methylamine HCl is colorless. We aren't using ACS-grade production techniques here, so don't expect ACS-grade product. However, the methylamine produced by this method is eminently suitable for the many purposes normally intended and if allowed to sublimate some when heating, no adjustment for "purity" or "water content" need be made in subsequent uses of it. [I can't understand how he can get 200g of product. 140g hexamine gives 80 grams of NH4Cl, and HOPEFULLY more than 100g of methylamine]. If the crystals are opaque white and do not deliquesce quickly in air of average humidity (65% rh), they may be contaminated with some Hexamine or some bizarre polymer. [Or ammonium chloride. Recrystallize from methanol, then wash with CHCl3]. Washing 100g of the crude product with 100mL of Chloroform by stirring in a beaker then filtering, repeated as many times as necessary, will remove Hexamine. Methylamine HCl is insoluble in Chloroform whereas Hexamine is at the rate of 1g to 10mL. As a final note, I have been informed that hexamine is available in some areas in the form of "fuel tablets" for small camping stoves. I have received mixed results from various individuals using this so, as the saying goes, Caveat Emptor.(the fuel tablets are the bomb, if still available, and the faintest smell of ammonium chloride is always present but SWIM never cleaned it with chloroform and product still produced so...)
There's also a good read by Osmium making methylamine this way that is quite helpful. I'll see if I can find it(or it may already be in that write-up..read that..it was written during those times and is much more concise with the play by play tricks and what-nots..

However, this is not an optimal reaction, because AmCl is present in excess and some ethanol evaporates. The version above means to correct this. A dash of HCl might help things along by catalyzing the esterification.

xBee has done a slew of methylamine synth's and I got permission to post his notes.  The best one we've found using hexamine is baalchemist's fav synth.  And the tip of using boiling dry IPA to extract the methylamine works great.

So the following is from an old hive post by baalchemist, with notes and updates by xbee from many trials.

Baalchemist Favorite Methylamine Synth (with Notes by xBee)

Bill of materials

• HCl (28%), 480ml/mol of HMTA
• HMTA, 140g/mol
• Isopropanol, 1180ml/mol HMTA

SPECIFIC BOM EXAMPLE – 4 MOL BATCH

• HMTA: 560g
• HCl (28%), 1920ml (make it an even two litres)
• Isopropanol: 5920ml (call it 6 litres – 1210 followed by 3x770 + 6x400)

Example of procedure
[NOTE: ½ mol batch size]:

A RB flask is charged with 240ml of 28% HCl and a stir bar.  Stirring is begun, 70g hexamine (“Fuel Tablets”) is added to the flask, and the glassware is set up for a vacuum reflux.  Vacuum is applied (c.a. 20-22” Hg) and the flask is heated, but only to a gentle reflux [stirring continues].  The reflux is maintained for about 3 hrs, then the glassware is changed for vacuum distillation and the solution volume gradually reduced over several hours’ time.

Volume reduction continues until only a “mush” [slush] remains in the flask [no fluid sloshing around!].  The “mush” [slush] is made of methylamine HCl, Ammonium chloride, and what’s left of the water.

Working quickly so as not to allow the IPA time to cool, the mush is extracted with 4 110ml portions of DRY IPA.  For each extraction, the IPA is dumped into the mush, the flask is swirled to dissolve as much MeAm as possible before the IPA cools very much [perhaps a short time refluxing would be a better approach – eliminates rushing], then the IPA is decanted from the mush and the next 110ml added.  

The four extractions are pooled and the IPA removed under diminished pressure until, again, only a yellowish mush remains.  This “new” mush is in turn extracted six times with 50ml portions of DRY IPA, working quickly and decanting as one did earlier.  The six extractions are again pooled and, as the IPA cools, crystals will/should spontaneously form.  [NOTE: six extractions are nuts – suggest 100, 100, 50, 50 instead of 6x50ml]  The pooled extracts are placed in a freezer for about an hour to further encourage the MeAm to crash out.

Once crystallization is complete, the cold solution is vacuum filtered to isolate the crystals, which should represent about an 80-95% yield.  The crystals must quickly be stored in an airtight container as MeAm is hygroscopic.

Points to note

• Ammonium chloride begins crashing out somewhere along the way [depends on vacuum] and it will eventually stall the stirbar.  One can/should remove the NH4Cl when the stirbar stalls; the subsequent extractions are then much easier.
• A 4 mol batch is the most one can squeeze into a 3 litre flask.
• Refluxing instead of adding boiling IPA seems to greatly accelerate MeAm extraction.  Consequence is that 3rd and 4th first-level extracts seem to be primarily ammonium chloride (soln is also cloudy as well rather than clear like the first two).  Although it is also possible that the two litres had some water in them even tho they should not have.
• Three hours reflux is NOT enough – more like 5 to 6 hrs needed.
• One MUST add the HMTA to the acid, not the other way round.  Especially, don’t dissolve the HMTA first in water – yields REALLY suck.

Salat (and xBee)

This looks a hell of a lot easier although I've yet to put it into practice:

100g hexamine (pulverized fuel tablets) and 30g nh4cl were added to a 1L rbf, followed by 120g den. etoh, followed by 330g 31.45% hcl.  This mixture was stirred vigorously and heat was evolved.  Gradual heating was applied with an oil bath (took three hours to reach >60c).  Two layers formed and distillate was collected between 34c and 60c with the majority of it around 55c.  Once no more distillate came over in that range, the heat was turned up and the remaining alcohol was distilled out. The flask was then cooled to room temperature and the solids were filtered.  The water in the remaining mixture was then quickly distilled away with an oil bath of ~150c.  The isolated methylamine was recystallized with anhydrous ipa to yield ~120g meam.hcl.

Hexamine, hcl and reflux does in fact work fine...

Otherwise caffeine in a concentrated lye solution and distill off methylamine. 100gr caffeine has about ~15g methylamine yield.

If you do the reaction in anhydrous ethylene glycol (antifreeze) you can distil off dry methylamine gas.

so why ask for advice?
if you know better no need to ask us.

you don't need a condensor just a line of tubing sealed with ductape to a beer bottle in a pot of boiling salt water (boiling at 106) connected to an aspirator running the *slightest* vacum does the best job of making methylamine hands down because it converts all the formalin to methylamine it does'nt come back as dirty yellow it comes back white you don't even have to recrystallize it it's less hygroscopic because it's pure easier to do things right in the first place.
than be lazy and work twice as hard in the end cleaning the shit up.

Couldn't one, if they chose to use lab glass, hook up a vacuum valve type thing inline within the tubing to the vac pump, and use it to dial in an amount of vac that is just right? What are those called again, pin-valves?

Seems like jon's way requires some way of dialing in a slight vac, so why not (if using a strong vac pump) do it with precision. Don't they make them with vacuum gauges as part of the thing too? I could swear I've seen those. With a gauge, one could reproduce the right vac on subsequent operations even more easily.

the just right vacum is done with an aspirator easy to dial that down just lessen the flow of water.
my favorate part of that reaction is cracking the 32 or 40 ounce what have you beer bottles open and guzzling the shit down.
you'll know when the vacum is spot on because all the co2 can be seen bubbling off the top not the bottom that was the idea to pull co2 out to drive the reaction forward and it works dandy just gauge it by eye.

you should use a saturated salt water bath because the temperature goes between 104-106 106 being optimal you can always tell you have achieved the optimal temperature when co2 evolution becomes vigorous.

you need to dilute that acid you can't just use it straight you can but it's not advisable.
use elusis's dilution in the methylamine from hexamine faq
i'm not a genius i just spent a long time doing the same thing over and over again.
let that cool all the way to room temp or you'll be filtering endlessly.
use a fan to cool it quickly.
also use your nose it should smell of rotten pussy with no detectable hints of formalin (sorry ladies)

another reason to use a slight vacuum when making this amine from hexamine is that it
slows down the dimethylamine being made there for creating more mono methylamine.

this will make it so you dont loose as much weight when washing with dry DCM
to remove the dimethyl amine impurity that arises from making this amine through formaldehyde
and ammonia.

actually at 106 no dimethylamine is made

no one in thier right mind would buy that.
some people are sting op's others are genuine outfits that sell hot chemicals for a profit.
the best way to find out is to order a non-suspicious item from them and see how they declare it to customs and where the package came from.

only one way to find out, they are purportedly from overseas but that could be a ruse too.
so order something benign say you don't want to pay hazardous material duties and see what they say.
i've seen digs like this before.
just see where they do business off ebay so the pigs aren't privvy to your business.

yeah like i said there are a lot of foreign outfits that advertise there the trick is to find out where they do business off ebay because private does'nt really mean private.

that's what they do they pose as an overseas outfit to make people comfortable.
what did you do look them up in whois?
they say are in henderson, nevada
you know you can look at those websites that the dea run like that one for example and learn a lot about what they are looking at.
suprize! suprize! SOCKS error trying to get to them behind tor, these guys really are fishy.

just extract all the ammonium chloride with methanol.
if it is offf color of the crystals are inconsistent you evaporated too much and methylamine co-precipitated
that's how you correct that problem.

yeah that's the idea extract the methylamine out with alcohol.
you would'nt need to do that if you crystallized the ammonium choride first.

yeah i didn't record my yields but with a minimal vacuum i didn't crop any ammonium chloride so i know yields were pretty high.
temperature control also helps things greatly.

jon if temp. is kept at the sweet spot for the 4 hours, no need cool down and filter the amonium? you put in the bottle and keep the temp at 106 then add vaccum??? or the whole thing its done at the bottle and you just add the vaccum.... sorry just got a lil confused. bright start filter couple of times, and the other paper on rhodium filter once before rising temp. and sassa also filter once. but if keep at right temp no need to filter? and you dont rise temp when adding vac? keep at 106?

i saw at a pond shop those old coke bottles, of 1500ml they are very cool might work also.

thanks
peace

no you have to cool it down and filter it periodically when you see methylamine crystallizing on the surface during volume reduction under vacum allow it to cool to room temperature and filter it off.
continue reducing then repeat this process.
if it's done exactly right you won't need to separate out ammonium chloride at least that's been my experience.
and, furthermore the methylamine salt is less hygroscopic and easier to handle when it is purer.

at my altitude salt water boils at exactly 104...... would this do the job? since water boiling at 104, i believe the contents will be boilling at a lower temp. correct? would these 2 degress make a big difference? would jons method still work with minimum amonium back, with the water bath boiling at 104? or should i just separete first crop?
thanks
peace

using 37% formaldehyde should water be added?
bright star uses Paraformaldehyde and add water, also he states that if using 37% solution water still be added....
now the picture easay on rhodium does not add water, and ratios are a bit different.....

can one use bright star ratios with no water? since using 37% formaldehyde? the ratios on the picture essay, and the bright star paper are quite different....

does it make a difference if one uses jon method with the vacum, but using 37% formaldehyde solution instead paraformaldehyde? should water be added using 37% solution? or can just make 400ml 37% formaldehyde with 135 amonium no water and slight vacum? tryed different ratio (from picture essay, at rhodium) tryed its ratio with slight vacum and  totally failed!!! now i see why, tryed 550ml 37% and 250gr amonium, maybe thats why yield sucked unlike jon experience.

apreciate any help
peace

I havent seen this synth detailed clearly here  (esp for you NBC )

Hydrolysis of Hexamine to paraforamide

140g of Hexamine is carefully dissolved in 400mL of Muriatic Acid (31.45% HCl) to which at least 100mL of (preferably) absolute ethanol has been added. Add the hexamine slowly while stirring vigorously and with good ventilation as some nasty fumes are produced. Allow all to stir at room temperature for at least 8 hours but preferably 16.

The yield of Methylamine HCl should be around 200g as white deliquescent crystals.

d) Notes on the process

If the crystals are opaque white and do not deliquesce quickly in air of average humidity (65% rh), they may be contaminated with some Hexamine or some bizarre polymer. Washing 100g of the crude product with 100mL of Chloroform by stirring in a beaker then filtering, repeated as many times as necessary, will remove Hexamine. Methylamine HCl is insoluble in Chloroform whereas Hexamine is at the rate of 1g to 10mL.

It has been determined that the best batch size is to process 70g of hexamine at a time. This is primarily due to the fact that the amount of heat necessary to boil something increases exponentially with the volume. It seems to normally take 4-6 hours to fully concentrate the methylamine solution with a 70g batch but as much as 16 hours to do 200g. Of course, the solution can be split up among pans to evaporate, but try and keep it at 100g expected yield per pan to get the best tradeoff between time and volumetric efficiency

Hi everybody again guys!glad to read you again!i'm not playing on the hobby since months,but i read you almost every day!
   About the methylamine synth with paraformaldehyde and ammonium chloride,i only can say it's so easy and fool prof,that anybody can follow it with 99% succes probabilty without serious skills on vacuum methods,distillations,...i made on that days i didn't know to operate a vacuum pump,a stirrerr,almost vent a separation funnel,but following bright star's article it's impossible to fuck up.possibly not the purest methylamine made,but i made reductions both with that methylamine and pure grade lab methylamine(it's possible to get it looking for a little without risk) and the results are exactly the same...more exactly i think i prefer salt made from brights star's method than pure methylamine....that comment about more intense high with final salt it's not a childs tale,and when i had both types methylamine,i used to prefere the less pure.yields where exactly as good too.
    I remember the most tricky part of reaction,after get the crop of non reacted ammonium chloride,when you are reducing the solution and aplying vacuum at the end to ride off the water,i remember to put the vacumm  pump to max.,and not able to understand when all the water was out,because i was waiting for a crystal formation on liquid surface in the flask....i was stressing the solution with lot time max vacuum and posible high temperatures than 106 celsius,waiting for that crystalls,and possible subblyming that liquid methylamine....when i was sure the reaction failed...disconected the vacuum and heat,and when i was directly go to discard the solution,something orange-red, saw started to solidify as a white chunk....putted quickly on a beak,and on 20 seconds was 200 gr white rock.
    Take care to not let happens that...because when you want to use it and weight like 40 gr that stuff,break that rock was impossible!...so a pain in the ass to work with...and important,,,allways wear gloves,the smells fixes to hands,cloths as hell,and it's a pain to ride off it

EMTWC: I have issues with your language already, and it's your second* post. My english translator breaks on your post for whatever reason, I apologize.

no fa fa foolin

don't believe post was pointed towards dreamOn, but

did you have something positive to add?

there's 2 posts

He did have something positive to add, he was explaining that your random broken English jibber jabbering is making it hard for no English speaking members to read what your writing. He was much nicer about it then I would have been.

it's really teperature
see at 106C bubbling kicks off vigourously you know you hit the g-spot
once that's happening just apply enough to cause the evolution of co2 to go from the top.
but no more or you evap all your formalin and the reaction fails.
