Title: will meth freebase come off with toluene in
Post by: tropine on October 17, 2003, 01:53:00 PM

a vaccuum assisted rotovap?  Toluene does have quite high bp. so I am worried that in the rotovap, the meth freebase will distill off with the toluene?

so long as you are not pulling too low a vacuum you should be ok.

The boiling point of methamphetamine at atmospherical pressure is 209-210°C, so it is very easy to separate from toluene, as long as you do not use excessive vacuum and heat.
