How much NP?

(1/3) > >>

Swim UTFSE looking for the ratio of freebase to non polar solvent to use when gassing.  There does not seem to be any concesis on this topid.  He Has seen any were from 8 to 1 or even 4to1 .  Also are you supposed to gas slowly or just let her rip?  Any gassing tips would be great.

jackhole:
4 parts solvent to 1 part base is fine. But don't go below it. And make sure to move around the gas dispension tube when gassing the solvent so as to avoid clogging the tube.

He did a standard A/B extraction and got about 30ml of very light brown oil.  The oil is said to taste exactly like the other MDMA that he has tasted.  He is thinking that he will distill the oil but is not too sure because he fears that he will loose too much to the glassware.  Is it alright to just put the Freebase in the NP and gass?  Last time he gassed with out the A/B and got crappola

jackhole:
You don't have to distill and your customers won't care, but over the long-term, serious side effects can induce from undistilled MDMA base contaminated with intermediates. These intermediates can alkylate your DNA and thus increase your risk for cancer. So, if you care for your health, you'll distill and sacrifice some yield. On the other hand, if your eye is on the dollar, just crystallize your product.

Btw, recrystallization cannot remove the impurities that a distillation can. For a pure product, you MUST start off with clean precursors, perform the A/B correctly, distill, and follow that by a few recrystallizations. Hope this helps.

If your amount of freebase is so small that regular vacuum distillation would cause too much losses, you can always try to get hold of some micro-distillation apparatus (suitable for volumes of 1-10ml  ;) ) or some micro-scale distillation rig - or even better use steam distillation (distill at atmospherical pressure, together with water). Although it may take some time (MDMA freebase isn't very volatile with steam), the purity is as good as with vacuum distillation, and the losses are minimized. Downside is the long time it needs and the extra a/b, drying and solvent removal you'll have to perform afterwards - but it is worth the work.

Together with max. 3 recrystallizations (nice dual-solvent/cooling procedure, not evaporating everything or flooding with acetone!), you'll get an outstanding purity, and gassing becomes alot easier, too!

(promised!  ;) )
