Distillation and distillation systems

[Mr Good Cat]

Is it convenient to use distillation (or vacuum distillation) system to distill the freebase? Or the yeld in this case is too low?
As I remember, boiling points of amphetamine family freebases are around 105C, so probably it shall be around 85-95C if done with vacuum.
What temperature shall be kept if done without vacuum in regular round bottom flask?

Policja PolskaHello, dear. I strongly recommend you to carry out steam distillation of your amph/methamph free base. Look at video about this.

They make an azeotropic mixture. Water decrease boiling point of amp/meth free base.

G.PattonDoes this work with MDMA as well?

G.PattonWhy you don't use hexane to bubble, then your ph will always be correct.

And after your lye and you vacuum distill it again, so you can directly pour cold HCL on it instead of generating gas to create directly crystals your red color doesn't make it suitable for crystal growing the shards will be cloudy because of the low P.h.

Jordan BelfortHi. Can you explain what exactly do u mean about hexane?

Yes, MDP2P can be steam distilled but you're far better off distilling it under vacuum. I've used steam distillation before, and you need a large volume of water to get the MDP2P to come across and the separation isn't all that great (I remember something like 25-100ml/1g or something like that).

Hello, yes, but it isn't recommended.

G.PattonOh wow yes that's too much water. I have a bunch of MDMA that's too dark to sell quickly. I wasn't able to get the reactor to function properly under vacuum. Do you recommend distilling the pmk after wax conversion or the MDMA freebase?

G.PattonIf you bubble in a non-polar solvent, except xylene because it gets reduced ( i found out with expensive base inside ), it participates out as an salt. excess HCL goes in the air.
In general all impurities stay then in the hexane layer.

And instead of cold acetone washing, you can also wash your meth in hot hexane.

TweakerIt is easier to recrystallize MDMA after synthesis.

Jordan BelfortNice Idea! Thanks for your explanation.

Jordan BelfortJust got a similar one as well, with the water vacuum pump I use, problem is, it can pull only up to 300mmhg, too weak, even the handheld vacuum pump isn't strong enough.

Any recommendations on which vacuum pump to use for this? Will be doing research on which one would be best before just blindly buying whatever is overpriced

rothschild33Hello. I would recommend you a rotary vane vacuum pump. Read more => Providing and application of vacuum in a laboratory

 

[Tweaker]

You mean distill? The temp is quite high. The reactor didn't want to mix while under vac.

TweakerWhen I said recrystallization, I meant recrystallization. Not distillation.

G.PattonI'm not sure what you mean then. My original question was about distilling pmk Vs MDMA freebase
