Hey people! This is my first thread here, I have done a lot of search about ephedrine extraction, but i couldn't find answers for my questions, so here we go:
I like to take ephedrine, it awakes me up and helps me getting through my day. I live in Brazil, and ephedrine is only avaible in combinatios with acetaminofen. As far as I know, that is nasty stuff, bad for your liver. And since I love beer, mixing both might be a little bit dangerous. Well, I'm not sure, I just want to remove all the crap from the pills, and be left with ephedrine. I have found some ways of extracting ephedrine from pills. A/B extraction and extraction with methanol, acetone and toluene. The A/B looks a little bit weird, because ephedrine base is slightly polar due to the hydroxyl I think, and it is soluble in water....I'm not sure if it would work at all...And the solvent extraction...Well...I don't have acess to methanol, but I can easily get 100% ethanol from pharmacies. Acetone is only avaible as a mixture with ethanol, benzophenone, some kind of seed oil and a corant. Can I use it? I think that maybe distilling the solution with a vigreux column would work good, right? And about the toluene...This one is a problem...Nonpolar solvents here are impossible from obtaining. I can get some impure hexane, distilled from some kind of cleaning oil for cars. I have acess to querosene and a little bit of petroleum ether. Ether is like impossible to get. They don't sell starting fluids here I think. I have checked some huge supermarkets, but I couldn't get any. In this case, what am I supposed to do? Ohh, and by the way, those are the impurities of the pills:
Starch, pregelatinized starch, sodium starch glycolate, cellulose, titanium dioxide, magnesium stearate, hypromellose, macrogol and polysorbate 80.
