Easy correction for too much acid.
Have you ever added a little too much HCl and watched the pH of your M
drop down to 7 - 6 - 5 - 4 - 3
Can't simply add a base or neutralizer unless you have an affinity for
salt and lots of it.
Do you dislike the idea of taking it back up to pH 12+ again......,
removing the lye, rewashing, and then adding d-water and re-pH the whole
mess just to accidently overrun it again 7 - 6 - 5 - 4 - 3.
Did I fail to mention "loss of product", and the "loss of your time".
Especially since it is totally unnecessary.
What do I mean unnecessary????!!
Yeah, you don't have to do that shit, it is way too much work!!!!
You only over-ran the pH by a little bit, or maybe by a considerable
amount, either way, the fix is quite simple.
Remove a small amount of the acidic ----/water solution. 20-50 ml is an
average amount.
Add to this an equal amount of your fresh non-polar solvent.
Smack it good with fresh lye solution, be sure you get a pH 12+.
Shake.
Remove the lye water.
Wash with d-water once or twice.
Add the non-polar and ---- freebase to your separatory funnel
Shake
Check pH and, hey!!! pH 8.2 , your back in the saddle, slick as slime.
All set and Ready to overrun the pH again.
For those who have bits and pieces of M, from prior reactions, that were
not very tasty, or second and third pulls. This is the perfect time to
pull out that container of disgusting powders. Run a quick A/B to clean
some of it, then use the freebase to correct the too acidic solution.
***BTW A can of red devil contains 510 grams of lye. In a 1 or 2 liter
container add a little less than 1/2 can of red devil, fill container to
1 liter with
d-water(Viola) ~=~ 1 liter of 20% lye solution(ideal).

This is a great idea.Another one is build a HCl gas generator.No more PH
woes and no more
evapping water.Use for pill extraction and final product.

Have not been too pleased with outcome of gassing, perhaps I should give
it another try since you seem to positive about it.
What do you suggest Ether, toluene?
Bubbling Air through an HCL solution then forcing it through a solid
drying agent then the ---- solution is easy enough.
Do you use a drying agent on your non-polar solvent first and what works
best?

Gas gen was dripping HCL onto conc H2SO4.This is passed thru a washbottle
of conc H2SO4,and passed into freebase/toluene.Crystals dryed over buchner
and washed with a little acetone.Results were good.Next time will take
your tip and use a little calcium chloride to dry the toluene first.BTW
this was first try of this method .Any ideas for refinements appreciated

Sorry,
I have a habit of questioning every step of every procedure to be used.
I don't mean this to be a pain in the ass, but since your willing to
exchange ideas, let's begin.

Why use potentially deadly H2SO4 when all you care about is dry HCl gas. A
simple air pump through liquid HCl is sufficient.
And why dry with H2SO4, it is a nasty bugger especially when it begins
that vaporous shit.
Ever consider
powdered rock salt $5.00 for 50 pounds, a tube filled with this salt, HCl
gas passes through the salt but water stays with the NaCl. The rock salt
is used because table salt is hydrated and the particle size is such that
it will not suck in a lot of water.
So it will not tend to solidify in the paper container.

Sounds a lot nicer.Im used this method cause I had both acids on hand and
got good results
Another from Vogel drips HCL onto NH4CL.I will try your method as it seems
most safety wise.

Re: Easy method corrects pH(too much acid) Reply

Using a gas generator for ages, I leapt at the chance of a low odour
method to replace it. The lowering of ph using Worlocks method is almost
as troublesomme to me in it's own way, It takes me ages to get it right,
and then evap the water !
Any ideas folks, any inkling at all how long that shit takes to go away ?
Water has become one of my least favoured solvents.
Gassed crystal is much smaller in size and is much more uniform in shape,
but it is not as good as evapped super solvent after careful ph adjustment
and seperation, needs rinsing again or recrysto..
Worlock, have you considered a two solvent recrystalisation of your
product ? The resulting needle like crystals are about 10mm long and clear
and crunchy. It is a really nice purification in a fine tuning kinda way.
I got all ass about. I can make showstopping crystals, of fine quality,
unfortunately in about a 20% return. I suck !
but it's so fun to hang out with me that I just put up with myself. Now I
have the feeling I am meant to be together and fate set it up well.
Worlockian, please mail me sometime soon and I'll answer after I have this
little snooze that seems determined that it's time is NOW

a better yield and as you said beats evapping water.Please tell more of
your method ie solvents etc Yes those fumes do suck a bit

Chem GUy is proababbly alot like me and dont waste his time when
working.....Um it is ussually the first time it works in my case.....um
yep I try abuncha different things with a new rational not simply
following directions but adding a diferent approach all together
usually....No being how I find sucessfull divedents at about a .25 sucess
rate according to theory and wacko at theorums amazingly they work? Ok so
thay want to make some {fill in the blamk] um so it works the first time
when gassing,,, um does this means ya tried it and we sucessfull in a
procedure that is widely applicable, others say I am right over nighty
percent of the time in theory and after working the bugs out of it it
could be considered over nighty percent good advice.....Humm so not to
spoil anybodys fun but how many different things have we um discussed???
Oh the most important ellemental thing is gona be launcehed soon....Do it
your own high pressure gas source for air or anything pressurized say
hello electricity and gass???? Use I want to run stuff on numatic powered
by in from electrolysis of gas and as the resultant haave a side monopoly
on the idea of it so all you inventors nnd big mouths start talking we
need this numatic powered motor for transportation and all kinda stuff see
this is run formm electricity and battery and now ya got another thing to
save the thrusters in??? Sounds fun dont it imagine the security if it
all them big tanks and stuff might just mind there own buisness
aferall.....Ever seen a torpedo of busted regulator go whooshing across a
block through a few buildings,,,yes I am taling mega potentialand along
with the cold fussion stuff ya got it made in the shade

Re: Easy method corrects pH(too much acid) Reply

Chemman,
I tried many solvents and preferred toluene over them all, it must be
dried thoroughly with pref.magnesium sulphate or at least allowed to stand
for an hour or more before decanting to a clean container. It seemed to
hold water very effectively and that causes problems.
The bubbling kept fairly slow and the crystal filtered out numerous times
rather than going till it is impossible to tell if it's done, always
yielded cleanest and greatest yields, this gives the solvent a lttle
freshen up when you rinse through the filter cake and add this to the pot.
Also, I think you avoid uncrystalised product from getting caught up in
the drying cake.

Re: Easy method corrects pH(too much acid) Reply

Wheather or not the special circumstances will hapen readily from small
addative improvements is questionable. Different solvent mixtures will
produce notable differences in product, dependingn on crystalizzation tech
employed such as evaporating from water, imagine the solvent let cure in a
mix of water and solvent, at ambient tempature asistd by fluxing tempate
gradient to alow spontanious crystallization within the mixture, as this
happens it is thermoinsulated in a colller jug thermos and ttempature is
adjusted by allowing heeating and cooling much like outside in the fall.
The crystal appear in fluid first and them sublime onto the walls sooner
or later the entire is suspended onto the wall of the thermous, this is
scrapped and reentrained into solution for final XTYLS, acid can be
cleaned prety good this way. The adjusted acid water is alowed to drip on
drop at a time from the top and it falls through a more boyannt solution
wheater or how many different layers is really dependent on pressure and
tempature, it cold well be ya will benifi from sonification process as
this causes chemical transformation at an alarming rate considering
prressure tempature critical controled equipment, aotomating the device
will provide simple and long term benifit for all, ussing the available
and simple chemical stuff and rembering this speeds up nearly any reaction
where evolved gas is a factor I would not be supprised to se the yeild and
constitution of most product to jump. Allowing pressure to build and at
the same time causing the solution to ccavitate will result in
instantanious reaction, rembering the bubbles formed by vaporazation and
allowing gass extracted to be reformed into pure solutions from generated
gas by ellectro and sutiable uV light wich also alows for a heat source or
sink, dont forget that ancient ice making machine history, the whole thing
can be as complex or simple as it needs to be, allowing water to drop
through or float or sink is very possible considering tempature and
pressure,, the better system is not a technological spagattie maker it is
a mix over of simple solutions from ready available products and
purification is not necessary, as the volume of the mixxutre is not
critical in any regard, having the multi role of each component mapped,
becoming famaliar with the different employment techniques, we rach a
technological standstill in progress to the avrage denezin of the domain,
I am glad it has reached this point of finality I have been waiting I am
very proud of all everything having been layed aside and discussed as it
should be and from a respectfull and compassionate counterport. I am
looking foreward to doing getting back to the discovery phase in the
researching area, although a big breakthrough at this point would be a
little bit much to ask for, I have had so many of those they seem
commonplace now. what we do with these new ideas is put them to critical
application this is not allways appreciated, by shall we say most of the
mass, so please to use diserfication in your approach to reporting these
new developments, as the refining of the past echniques has done much
dammage to the avarage denezin of this domain, feel free to employ any
idea or all and give credit to whomever it suits at any paticular time, we
are good at this, and it is a good thing to do what suits whomever may
become appreciative and linger for advancing wisdom dished out sutiable
protions to the conceering dispensoary guide. Allthought the advancing
technology repot is commencing at an alarming rate and due to past fears
having becomee reality do not let fear guide the path to harnessing these
new ideas or/ do not imprsionate the idea in fear of retalation, as so has
seemingly been used as a raport to deny the truth to those of the mass

all esentuallity an absolute foundational principle to guide it. A
specific example that may cause or curative efect in minuratuallity in
relation to individualistic and unique circumstance not well reported and
cited as a generic thing and gets a generic an equal thing in return, thus
much time and effort is used to guide the thing to get it off the ground,
most of this effort is a waste of time the most important considerations
and time concerning repetious events and reporting should concern bodily
harm that migh tcome to an individual whoo could be nieave in regardss to
loss of function from preeforming somewhat complex and crittical
procedures that often result in a dangerous event, all in all any
advancing technique should empploy the most safe and clandestine method
available and especiallly if reporting from a know end to the means, thus
much effort and time --is waste of time. is not suited to this forum
presently is the opposite reflection of this end tuition that must not be
allowed to bear friut, and do not hessitate to add simplification to the
problem by taking awide approach, this is ver helpfull for all and I am
impressed by this conuanial report as is at is communal in essence the
overall token of advancement the greatest weapon will always be
diversification and infecting the whole with the benifit of the approcah,
the society sufferes greatly as a result due to non diserfication on the
applicatory phase of the method employed to keep rule and order to a
minimal lode of overburden to a few selective posts, this should be
tolerated and is the result of the guides mistakes in providing to narow a
path for others to follow, the method is simple and technology employed
shold not overgrow the common knowledge, because if it is not common
knowledge even if that means with a selective few who want it and have
found them selves in company containing the essential foundation for
benificary entitlement do not for any reason consider it a waste of time
to help such as is fit to be called the critical measure of need, or is
someone genuine in there need? Hummn so the enemy is this thing not them
who dont what to know nor is it those who want to be secretive about it,
the enemy is the effect and equal and oposite reaction needing to be
entered into the ballance, this can be manipulate compassionally at will
if necessary, but never undermine the power of it or it will take
possesion of everything at once and cause ruin from lack of respect ofr
whatevr principle it may be, allways be dilligent and wait for a guinine
offer for comradery as this is a rare opurtunity to form a monopoly on the
critical stuff alowing all to patercipate therin the exchange of it and
alowing competent and discerning individuals to add to it as they seem fit
to do so at any paticular time. Everone has ups and down and the
interesting inviduals invested with power in most situations are those who
struggle at it ofteen they have become experts as the result of contunal
need for repair and are very experienced it applicatory phases of the
whatever it is that is seemingly the problem at hand, other times some may
appear to have a peusodo quaility of or about them but it is allways
undessirable in the end to end up with the non genuine stuff and this is
not allways an easy thing to discriminate, allthough on the surface it
seems well enough to jump to conclussions based on a little action or time
vested never employ that you have wholey understood even the foundation of
what has seemigly been asserted or testified upon the thing that is built
in short time and does not bend to suit individual needs and alow
diserfication, look around I say and see the whole in extenction just as
we experience the growth and flowering bloom of new expectations it is in
the application and simple aplication at that that we have become so
talented at ussing the common thing to add justification to our end, thus
are ways are distinct and the diversity is seemigly narrow, do not narrow
this path but make it wide and jump from it as seed to through the wind of
time and allow it too, and it will be that what you leave will be better
than what you found but the application o this genera may nt well be
employed to justify the end to the thing as you might have expected as
there seemingly is allways a need to leave things left undone as to the
whole we who are nowing and following the thing need still to know the
difference between reading and knowing a thing or situation based on some
things that are not apparent in the litature, and alot of fakes have
become know in through the simple reading and comerce of trading this as a
mater of something to regretfull of this the lessersdie of the greatness
of the greats because they are allways seemingly in the relaxionary phase
after taking credits for the greatness umm we are aware of this conclusion
of the discoveries and the discoverories that resulted in ruin of an
advancing and wholsome thing of the overall objectivness of the situation
and allways take on the guild position to a overzealous seeker, who might
benifit from your lead in comming into the truth of it...I must go stop

Have a quick question here guys, In my dreams the only hydrochloric acid
notme can get is the drain cleaner which has a very low amount of acid and
alot of other things, the bottle doesn't give details, notme can smell the
slight acid content but while trying to add the acid to the lye
water/colemans notme can't seem to add enough the cabbage strip stays
green to a quick yellow no matter how much notme uses..Is there a way to
make this mixture of partial acid more potent by removing the other junk
and concentrating it??? thanks..
Peace!

Re: Easy method corrects pH(too much acid) Reply

My first problem with gassing was the gas has no on off valve.
A slurry of NaCl and HCl, then adding H2SO4,
The vapors were viscious, the bubbling over ran the flask and gassing had
to be terminated. Forgot and used a plastic tube instead of glass, so
yield was suck, the taste was not great, and still needed filtering and
washing, then I wondered about chilling.
I have no problem adjusting the pH of d-water and ----, and dislike
evaporating water, so I keep it concentrated, when the water is gone the
crystals are clean and ready to use.
Once you have the freebase in toluene, after removing the waste/lye/water.
The crystalization from the solvent is clean enough, I imagine except for
the bit of remaining toluene, since nothing else is likely to precipitate
upon gassing.
With the waterevaporation any remaining waste crud that is water soluble
ends up in the product. A definite concern. To get this to a minimum
requires, three hot water washes after the lye water is removed.
These are done just prior to adding the final d-water that will be pH-ed
and evaporated.
You have given me an idea, it may be that the final addition of water can
be kept to an extreme minimum, so that little needs to be evaporated away,
decreasing loss to evaporation, and with the concentration very little
impurities may pass into the low volume of water.
Once thought that more water would extract the freebase from the toluene
better. But that is not the case multiple small extractions of the ----
HCL from the toluene using d-water will be much more efficient, using much
less water. But may present a problem setting the pH with each extraction.
Unless the water can be preset to the correct pH that will saturate it
with ----(it can), just keep extracting with 1-5 mls of acid water till
the pH of the water coming out begins to drop and your done.
The potential here is awesome no mo' pH hassle, set your water
concentration at a certain HCl level, add little amounts of HCl/water to
the toluene, run the water passed the digital pH unit as it exits the
toluene.

Can even imagine a drip system where acid water drips in the top and drips
out with ---- below.
Even if I don't switch to gas. Discussing this final process is well worth
it. Certainly it has already produced details that will be of genuine
benefit, and quite unexpected. Thanks for your comments so far.
One of my pipe dreams "assembly line speed"
add ephedrine at one end, the automated unit takes small bits of E mixes
in the proper amount of P and I2, passing it along heated tube where it
reacts, gets filtered, n-p solvent and base are dripped in, separated
using a holding tank, the overflow goes to a second holding tank, where it
is washed, the freebase on top overflows into a third tank where acid
water is dripped in , removed from bottom then evaporated to speed, at the
other end.

Re: Easy method corrects pH(too much acid) Reply

Worlock,
Soooo, What are you doing, and how did you get too much acid in there?
'Remove 20-50 ml'? From WHAT?!
So, by diluting your ---- solution, then adding base, you're hoping to
avoid... adding base? Does this not make sense to anyone else?
Definately, without a doubt, for salting out phenethylamines, I'm a 'gas
fan' until the day I die. Use anhydrous solvents fresh from the can, and
you have no worries. Barring that, anhydrous MgSO4 or Na2SO4. Solvent?
Toluene, DCM, pet ether, benzene are my choices -- in that order (hate the
smell, but love those toluene-precipitated crystals!)
Sorry, I have a habit of questioning everything too:
quote:

And why dry with H2SO4, it is a nasty bugger especially when it begins
that vaporous shit.

...As opposed to healthy, nurturing, HCl?! Firstly, its not so much a
dehydrating agent as it is simply a nifty trick to move the soluility
partition away from dissolved HCl -- the higher hydronium ion
concentration means you're already saturated HCl solutions (which is an
equilibrium of H3O+ + Cl- <-> H2O + HCl), is going to liberate the gas
from the solution. Yes, H2SO4 is dangerous, but so is HCl, and the
difference is less than you think.
Another method that some people enjoy is gently refluxing 37% HCl. HCl
forms a constant boiling aqueous solution of about 10-11%, meaning that
the remaining 26% can be utilized. Use an efficient condenser, and dry
with CaCl2.

Re: Easy method corrects pH(too much acid) Reply

I haven't gassed ----, but I have gassed a number of other things and my
experiences may apply here to help y'all.
When you just bubble air through HCl then dry through salt, you pick up a
shitpot full of water from the acid. It all can't be removed by the salt,
unless you have a BIG salt column. Same thing applies if you heat the HCl
and dry it the same way. Way too much water is transferred. There's a
bunch of ways to make dry HCl gas, just look around.
The method I use is to drip Sulfuric on HCl and dry the released gas by
bubbling through Sulfuric then passing through "Damp Rid" I picked up at
Home Depot. Salt helps in the HCl to pick up the water that is in the HCl
as well, but it isn't absolutely needed.
The dryer the gas and the dryer the solvent, the more crystals will form
and not dissolve in the water that is carried over. This bumps yield up a
lot without having to spend the time evaporating water.
However to Worlock's credit, the gas method is a real pain in the ass and
the water method is easy.
One of the old time visitors to the hive would place a small container of
HCl beside a container of freebase dissolved in toluene with both of them
in a large plastic bag. Apply a heat lamp and wait. The HCl will gas the
toluene and the toluene will evaporate out of the container and collect on
the bottom of the bag. Then, just collect the crystals that form and dry
them.
Sorta combined the best of both worlds. I tried this and with a couple of
tries made it work pretty well.
But like I said, I never make drugs so this may not work for y'all.

i got to go so real quick ya add h2s to a solvent to precipate epsom salt
not the other way it dont work that way althoght it might work a little
bit if ya desicate the stuff but this ussually drives off an ellement and
ya no longer have salt like ya had before if done carefully it does work
but never as good as good plain pure gas, see if there aint no water in
there then gas just rises out of solution unless pressure is not allowed
to escape in that case ya get an explosion or pop o f gas H@S is not
dangerous it does stink a bit alot it stinks but it can be ussed safely
and does dehydrate alot of different stuff will makes epsom of any amount
of water given time....

ussing H2S at a few parts per million alot of thigns could and can be
achieved over time. Understanding this take caution it can kill you, and
others if there were to be an acident in spilling or alowing a pressurized
contain of this gas to evolve from a solution like propane.....enough
said? Dehydration of the said salt drives off most of the water, but it is
slightly different than reported in the classical way it has some of that
ellemental water trapped in there as it crystalizes, the potential for
this kinda reaction in whole is not readilly being discussed, so I will
move on then....

Well if ya haven't tried gassing, try it trust me you'll like it much
better. One of the best benefits that you can get from this method and NO
other method is-->You get lets say a 1/2 gallon of toluene and saturate
the livin shi* out of it with DRY HCl gas, to the point where it gets
cloudy. This is acheived by bubbling, and bubbling and bubbling HCl gas
into it, until it is fuming. Stopper it well and fasten stopper in, cause
it will build slight pressure. And then when you need HCL toluene you
just add say 1 oz to say a couple hundred mls of freebase containing
solvent, and PRESTO instant NO waiting results, you know right then and
there if ya did things right or if ya gotta go back and adj Ph more to get
the freebase material to move into the solvent. One note I have done
things this route for yrs now, and the HCL mixed in with the NaCl to make
a slurry is an accident waiting to happen, unless you really know your
shi*, I'd highly recommend just using NaCl and H2S04 for gas generation
with drying thru H2S04. And as for dripping in the H2S04, you can do that
but remember you have pressure in the generator, and given the chance the
pressure WILL try to vent itself thru the sep funnel containing the H2S04
if things become too restrictive thru the bubbler. A more efficient
method I have found was to get a 1000 ml Florence flask(the kind that look
like a round bottom that has a flat spot on the bottom of it) then add say
an inch or inch and a half of NaCl to it, then get a vial type container
that will slide down the neck of the florence flask and seat itself into
the salt but is just tall enough not to tip over unless you shake the mix
slightly, then stopper it with a 2 hole --7 or 7 1/2 rubber stopper. One
tube runs to your gas drying H2S04 and the other is a pinched off tube,
that you can open when your trying to disconnect the generator from the
gas drying H2S04, without causing backpressure due to maybe pinching the
lines to get a grip on the tubing. Then VERY carefully shutdown the
generator by taking to the nearest sink and SLOWLY letting water run into
the generator, once the water has gone in a little you can add it more
quickly, and yes fumes will come out and heat will be generated by this
dilution, just don't point it towards anyone that you like, if unliked
well that up to you;-) I am welll aware of the fact that it isn't a good
idea or proper lab technique to mix water into acid, but if you have used
the generator for any length of time, the contents of the generator will
be mostly NaS04, and hasn't caused problems for me in the hundreds of
times I've done it.n The vial type container can be glass or plastic, but
if it is glass, shake carefully unless you want to crack the florence
flask(I've done it once), and it should hold maybe 1 to 1 1/2ounces of
pure H2S04. Once you disconnect the drying solution from the system I have
found it best to connect the inlet to the outlet on this container,
basically just making a closed loop, so you don't have to saturate the
H2S04 each time you use it, just remember to change the drying H2S04 maybe
once a month, or when it starts to turn dark from a light yellow starting
color. If ya need more details let me know. Pyrex out

Well it is so common this idea that it could be not considered
clandestine. This is a critique ya as for it by posting here this is what
we all want.........
Um it is a thing to get busted by getting and having this battery acid
around and the equipment has an oder [stinks]to it ussually, I have evn
pickep up shit from garage sales still reeking of it,,,I allwways find I
like people seeling stuff like this they ussually are giving it away by
the time I get friendy with them..........
Um well anyways there is noting to regulate the overpressure of the device
or hardware in the event of cracking and other stuff inocent people might
be harmed, from the resulting mixture of oven dried epsom and anytype of
hydrogen gas,,,,,
Hum so maybe ya should reconsider making dry gas another way, Improvements
are posted!@above???
Anyways it is alot better to make U own NAOH excess hydrogen and good
amount of HCL from simple thing really to simple....>>>>>
What the fuch is wrong ? do U NO a good idea when ya see it????

mrr pyrex,
Good idea using the pre-gassed toluene, one I have not heard of before,
but a method I intend to try.
The vial that is seated into the 1-1/2 inches of salt in the florence
flask, but is tall enough to not tip over......would you explain that
again, I'm having trouble visualising, what it is your doing here.
The vial about what size of (length and diameter) are you suggesting? and

How do you slip it down the florence neck?
by tipping the florance sideways?
Do you shake it carefully, then, to tip over the vial, releasing the H2SO4
onto the salt, producing gas.

buzzard,
Man, I am having a comprehension problem today,
Are you washing the toluene/free base with warm d-water 3 times, then
washing the ---- out of the toluene/freebase with a dilute HCl solution.
If so what is the approx dilution of the HCl solution?
And you can tell your done because the HCl wash solution's pH begins to
drop and starts coming off cloudy? is that correct?
Please tell me more about this method.

Cheapskate,
Thx for clearing up that erroneous method using salt and HCL no wonder I
had poor results gassing.
With all these people so positive about gassing, and the volume of water
to evaporate rapidly becoming a problem(after loosing a load because I
walked away, shit talk about making some smoke and getting over buzzed).
It is time I put the visionware aside and entered the world of gasers.
