SWIM would really appreciate some help with finding a suitable extraction for a nooB. i.e he has no experience with boiling solvents.
in his area he can only get hold of 60mg red-hots with a dull coating. (sudafed, non-drowsy).
could anyone help?

Do red hots come in 60mg. strength?

crush pills to fine powder(coffee bean grinder)soak in twice volume of dry acetone for 30mins--filter--throw acetone away--soak again with acetone--filter(this gets the red out)--mineral turpentine soak for 12 hours--filter--throw turps away---3 times pill mass volume of toluene--heat to 108c and hold for 8 mins stirring all the time(scraping bottom of beaker)--filter--throw away toluene--repeat toluene wash 2 more times--add 3 times pill mass volume of extraction solvent--stir for 3 mins and then let settle--filter--save solvent--repeat extraction solvent 2 more times---evaporate solvent slowly--then an A/B extraction----now your ready for the reduction--good luck

for the 30s----same wash--just drop the 3 hot acetone washes--add two cold acetone washes after the toluene washes (allow the pill mass to cool before doing the cold acetone washes)

Hello Red Horse, What your asking about is up and going. Back up on the posts and look for Pikk's post. Later

stupidity is some amazin ass shit too. the current pill formulas will not allow a water extraction. do you think that all these complicated methods for solvent boiling and such were posted for somethin to do, when a simple water extraction will work? use your head for somethin besides a hatrack.

Re: psuedo extraction
you cant use tap water either--the chlorine content will fuck the taste up badly

My bad! Didnt realize THE "Current Pill's" constituents had identical physical properties to psuedoephedrine. Like an ass, I JUST assumed that maybe their was at least a little varience. I figured hell, maybe a thermal solubility curve difference could have existed at 760 torr or any other torr for that matter. Go figure! Identical properties. Now thats some freaky ass x-files shit!

Re: psuedo extraction
kirby, I kind of like the taste of chloride in my methamphetamine vapor. Sure beats the sulfate, and base dont tickle my fancy either.

Re: psuedo extraction
Hey sparkel--
Do you have something you can enlighten us with, or were you just pissed at kirby and wicked for telling you what just about everybody knows about the huge majority of cold medication formulations containing pseudoephedrine? You said--
"My bad! Didnt realize THE "Current Pill's" constituents had identical physical properties to psuedoephedrine. Like an ass, I JUST assumed that maybe their was at least a little varience.

You think you can elaborate on this solubility curve for us?

SWIM dont know shit about constituents, thermal solubility curves, or fuckin torrs.
but SWIM damn sure knows about water, pills and extractions. SWIM mumbles somethin about over educated people and there desire to show how smart they are and go`s back into his fuckin cave

Re: psuedo extraction
OK, pure substances are only soluble in a specific solvent to a minimum threshold of temperature. A solubility curve is a graph stating how soluble a specific amount of a pure substance is within a specific amount solvent (usually in g/ml). Often times, chemist perform this operation by heating up the solvent to a maximum heat and dissolve the unpure-mixture in as little of the solvent rendering it a saturated solution. As the solution cools down, it becomes super-saturated (over saturated). Chemist who wish to seperate the mixture often throw a starter crystal in the super saturated solution to induce crystal formation of the substance they wish to isolate. The remaining liquid is filtered away from the crystals which are then dried. This operation is called "Recrystalization". Recrystalization is often times performed within oil and ice baths to regulate temperatures.
You will have to give me a couple weeks to be more specific about the solubility of gases within a solvent under various presures (the 760 torr thing). Class starts today, and Im attempting to get over a 3 month summer run. Help me, im falling out, and I cant wake up! Smoking desoxyephedrine and looking for facial worthy females on the internet makes for an unstudious student, so I had to throw in the ol towel and hopefully (prays) I can make it to class. (I cant even find porn with hot chicks anymore. God help me!)
Give me a some composure time guys, I and will attempt to bring you some more specifics (without <hopefully> pissing off the Govenernment, FDA, the League of Shadey Pharmacist, and especially the ALIENS)

Hey Kirby, I tried this method as you had posted the other day. After I have now evaporated the ethyl off, at the end I was expecting to see some white crystally, however after using low heat and eveping the ethyl I was left with this corn syrup, clear looking stuff and little of it.....WTF do you think?
