Im sorry i didnt put this into the chemistry forum, but for some reason it wont let me post there.
This system has been beating around in SWIMs head for quite some time. Steam distillation has been used for thousands of years to obtain the essential oils of plants and substances. I know that swim
can effectivly steam distill the ephedrine out of the ma huang plant, but not the pseudo, this is ok, because there is (to my understanding) much more ephedrine in the plant than pseudo, and the other two amines (I can remember thier names).
after obtaining the distillate, just adjust ph with dilute hcl and evaporate. theres the ephedrine. put the ephedrine in with your HI/rp reaction flask and continue reaction as usual. after filtering RP out of reaction solution, put your meth
freebase/ reaction mixture into the steam distiller, adjust ph to above 12 and steam distill reaction mixture. collect distillate adjust ph to slightly acidic, and evaporate.
Theoreticaly one should have just made meth without using any nasty solvents that stink and cost money.
What does everyone think of this, any ideas/critisism are accepted.
