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?

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

Does this work with MDMA as well?

 

[Jordan Belfort]

Why 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.

 

[G.Patton]

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

Hello, yes, but it isn't recommended.

 

[Tweaker]

Oh 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?

 

[Jordan Belfort]

If 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.

 

[G.Patton]

It is easier to recrystallize MDMA after synthesis.

 

[G.Patton]

Nice Idea! Thanks for your explanation.

hardest part about this is the prices of the equipment here

Here video of vacuum distillation live.

Just 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

 

[G.Patton]

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

 

[Jordan Belfort]

Connect two water jump jet's parallel (Y connect) you only have one.


And yes the best pump is imo q vevor pump 1hp like 10 CFM is rotary vane check Ali. Normal price 25 microns and does 15 000 liter airba hour.

Oh actually price went up from 190 to 315 maybe no stock in Poland anymore

 

[Tweaker]

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

 

[G.Patton]

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

 

[Tweaker]

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