If SLS is only slightly soluble in Toluene , then it will be even less soluble in cold toluene. This may allow you to mix a cold alkaline aqueous solution of the soap and ephedrine with cold toluene and separate.

SLS may be possible to isolate it in a middle layer between the polar and nonpolar using warm toluene, and slightly acidic water after shaking well, by making the solution slightly acidic. Ephedrine will be highly water soluble. SLS will be more soluble in the toluene.

If you must toss out some toluene to get rid of thr SLS then make your solution dilute and the loss od E will be negligable.

The sassage skin gots stuff in there use fish guts for all I care ever seen this stuff stretchy stuff huhg?

Note that one layer is insidde and the other is outside experiment with different ideas such as extraction through plastic baggies???

Anyways solvent stuff really sucks sucks sucks it taste shitty and all that too

Only the best will do did ya ever wonder what the PH of Propane was or maybe some CO2 and Propane mixxed Do you know wich addatives are added to which gasses and at what concentraation?? Thought so see they do teach people in school how to teach themselves they are only there to assist you cant make a good dr it takes spirit man to make something gooder.

Ya mix ya stuff with all kinds a shit a there are plenty enough procedures dealt here allready I must be moving to another board, um ya

Anyways fuck the salt up the ass it sucks NACL unless for ellectro give up the salt alltogether there are so many easier ways to titrate a solution and so many things are so much better than accitone and shit like is nasty shit taste shitty and sucks raw dick

Anyways do learn how to transform products from electrolysis learn the right solvent I am supprised you most of you get anything at all from the product and your commitment to finding a simple recipe, there is on and if I said there was gold over the on that mountain they wouldent look neither, unless I dig up a dead indian and display it for halloween, compleete with the pagamas

So understand a solvent layer ing effect
You can manipulate all kinds a shit and I hope they do illegalize the pills and solvents for all I care this is a great thing for us because then the uneducated swine got nothing but the besst of the best and I am talking some nity gritty shit that is so slick you are gona slip and slide all over the shit because I aint neither gona play nice no more and you are gona have to impress me with your input and creativity or I'll write a fucking book and pass it out for near pennies, well actually nothing at all cause it didnt cost me anything

The hive is cool and all it did the job for me but it is on a lame end and most all have either gain eledification for there pursuit or have been well have not been busy in the maner I would think or would aspire them to be to become in the mind and all

Frankly I dont like amny people and especially someone who thinks they can make a buck or something off my ideas, this is not for money this is for the mass of goodereers or anyone who thinks they got a good reason to do it. Fine get busy and get spun and all ya like untill you wear yourself out feeding this stuff like exotic ciggeretes to our communities is not helping one bit and the war on drugs has only done one thing in my opinion,,,,,,,,,,,,prejudice of meterialistic pig basterd in need of some gossip or action something to be aggainst

me would extract through a wick if needed but the only thing that works good is the ellectrogut thing, the gut is filled with stuff and tied shut depending on situation the microfibrils can be coerced to precipate by salting in with say maybe al foil in the solvent will work along the process some time ago, seems very few tried it????

My yield was up when ussing the or the quality of the yield was up and when I quite experimenting with al foil the yield and quality went down, the procedure is listed in the hive awards in the couch area, oh I used a laser to heat the solutio this was added to the comentary later as I attempted to repeate the process several times, I finally figured out what the catalyst was, although I still cant figure if the stuff rises on the ice cube thing is even better???

The gogo seems to be in the soap part???

The gogo seems to rise out on top of an ice cube????

the gogo is still real sulphy and taste like battery acid it dries my eyes out and there is no other precident except to make the product last for ever or nearly so, I really think they should tell the cunsumer how to rid the product of this garbage!

posted 10-03-1999 04:50 PM         

the soap seems to have the active ingredient entrained at a high persentage!

wen chilled the soap rises out of the solution if treated properly????

it did for me????

1-Water extraction ----->fiter.
2-Basify ----> filter .
3-Add freebase to acetone.
4-Gas with HCl.

the soap is isolated in concentrated solution it is not sucked of though a high percent of goods may be caught in the soap

then it is dried and then a bunch of solution is added, the trick is to keep layering it so it cant rise as it gets stuck

you will see this is only one contaminant causing XTYL problem it is easy to see the contaminant this soap>>>>means no problem

the microcellulose can be caused to plane like a compass point and it will filter upside down tho the ellectro is supperior for removing this as at superpotential the product acts as slush in solution

repeated ellectrocrystalizations will rid this compleatly of microcelluloses

I have not had the honor to meet sodium laurel sulphate, so my advice is somewhat
spurious and uneducated.

Worlock's advice about coldness is something I would try. It's easy to put in the freezer and see what happens: it's been known to coalesce some other evil additives.

Further, and this is true for several OTC's I've experimented with:

do not use water, use alcohols for the original grinding and mixing and basifying etc.

Alcohols have a quality of not being subject to bufferring actions like water: I think that several of the additives depend greatly on ionic combinations with the water to entrain or otherwise mess with the extraction.

Mixed alcohols and xylene are my preferred two solvents: and they HAVE to go in the freezer to differentiate.

Maybe alky's and colemen's would work too.

Do not overlook the Fman's references to electroseparation: supported by the Stonium(kiss!) contribution about it's usage in electrophoresis.

Please try the non-water and freezer method on a sample: I'd be really interested in the result.

But it is not a stupid idea for some who have tried it.

Anyways the buffer agent you need to work about causes a contact explosive when ya try to clean the product of iodine with sodium thiosulphate and then give it ammoni or something like the ammine

CH3CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2-SO4-Na

I would try to get rid of the Na, at least, to destroy this molecule's ability to dissolve in water.
With the orginal pills I would acid treat them with HCl, and wash with toluene, or a high weight alcohol non-miscible with water. The HCl treatment would do one of two things:

C12H25-SO4-Na + HCl --> C12H25-SO4-H + NaCl

Or

C12H25-SO4-Na + HCl + H-OH --> C12H25-OH + NaCl + H-SO4-H

I beleive that C12H25-SO4-H and lauryl alcohol are both insouble in water.

The only thing I would say is that I have not found it necessary to use methanol: the mixed alcohols from the hardware store seem to work fine.

The blender beats the hell out of dry grinding: separation of MCC can be effected by the sand trap that Prickleberry abhors: or as you said you can go ahead and saturate the alcohol with NaOH.

However, being the lazy guy I am I usually just more or less hang the pH sensor in the corner while the blender is on low, and add NaOH prill by prill until I get to 12 or 13: and then add an excess of NP and separate.

I have used xylene, and separate in the freezer, and find a lot of other gunk (like povidone) agglomerating under the influence of coldness. However, the Coleman's might do similarly, and with the advantage of discriminating against the guaifenesin,

========================

A friend of mine and I were discoursing about the use of charcoal lighter fluid the other day. I hypothesized that charcoal lighter fluids would have no reason not to include lighter parafin waxes in their blend: whereas Coleman's and similar would not include them because of the possibility of clogging the small orifices of some of the types of stoves that use them.

===============================

Prickleberry, I have done no illegal acts for several weeks due to local circumstances.

However, although you disparage the electro way, UF's seminal posting (actually the TRUE 1st interest posting was in ADC 2 years ago with the Hg cathode)

you will see it rise again like a Phx from the ashes of disdain.

The Lone Ranger presurized technique is pretty simple, and as good as the ZnCl2 as far as quality, which is better than the best glacial acetic technique that I have done at least:

but Chem Guy's Urushibara appears to me to be waiting for me to get back in action: which is both a surprise and a disappointment to me, it being so damn simple in concept anyway.

Maybe I'm missing something.

=====================

UF, you wre apparently "out of action" on vacation or something

when I posted greetings to you from an old friend.
