Gassing with mineral spirits

(1/3) > >>

wolfx:
Is it OK to use mineral spirits with an HCl gas generator
for MDMA ? Do I have to distill it first ? What would be
the best solvent for this ?

terbium:
You can't get toluene? It is probably a better solvent for the freebase. But if you can extract your freebase into the mineral spirits then it shouldn't be any worse for gassing than toluene.

I think gassing in toluene (or mineral spirits, or Colemans) is a bad idea. Better to extract the freebase from the toluene into acidic water using water acidified with HCL and then boil down the water solution.

In my opinion that is a bad idea.
Gassing is so easy, unless you have shitloads of impurities present it will ALWAYS work. Especially with toluene. I couldn't believe it myself, but when I tried that the first time I was surprised how well it works. A toluene A/B extraction layer, not even dried with drying agent will produce beautiful white product after acetone washing (which was simply added to the toluene afterwards and gassing commenced).

terbium:
I have never tried gassing in toluene, whenever I did it I used ether. So many people here seem to have trouble getting any product when gassing in toluene. I would expect HCL to be much more soluble in ether than toluene and wonder if this doesn't make a difference, especially in the dilute solutions of freebase that some people are using. Perhaps your addition of acetone to the toluene also improved the HCL solubility and thus the formation of the product.

Osmium:
The big advantage of toluene is that even when it went through an A/B process, it's dry. Ether contains lots of water and has to be dried, toluene will contain much less when you sepatate the phases correctly.
Acetone doesn't make a big difference, since there's only a few percent present (none at the beginning) when you add the acetone washings to the gassing solvent. All those filtrations and washes were done in a sintered glass funnel, adding only enough acetone twice or three times to barely cover all the crystals, stirring it around with a spatula and removing it as completely as possible by drawing air through for a minute or two.
Try it out, works like a charm.
