Precipitating dmt out of aqueous solution.

Hi fellow nexans.
I was a long time lurker here for the past decade, I used to have an account but it's so long I forgot about it.

Anyways, I found some old acrb lying around and I decided to do a stb. I am planning on salting it out of the toluene with vinegar and store the acetate, however the acetate is kinda a pain to deal with.

I had a thought that I've had before, but never knew if it would work so I decided to ask here in case anyone has tried it before.
Could I add sodium carbonate to highly concentrated solution of dmt acetate to crash out the freebase? Surely it cannot be that simple otherwise every one would be doing it, but I couldn't find a mention of it. I know dmt freebase stays dissolved in the stb soup but I don't think it's soluble enough to stay dissolved in a concentrated solution.
 
Hi, welcome back!

The answer to your question is (a qualified) yes; people have reported obtaining freebase DMT directly from aqueous solution. It would be a bit of a trick getting the search terms right to dig up the relevant posts, but they are there somewhere.

Vinegar and sodium carbonate might not be the best choice of acid and base [too weak and too fizzy, respectively], although they are typically readily available in food safe forms, to mention a plus point.
 
Right now I have a jar of DMT HCl in solution that I freebased with lye. All of the DMT crashed out and floated to the top, creating a yellow oily layer. I did a pull with hexane, but it wasn't able to pick up all the DMT in one go so I left behind some of the solvent on top of the oil layer, to protect it from the air. (superstitious about oxidation). To contradict myself, I also left the lid open, for 24 hours.

When I checked on it today the oil layer of DMT on top of the water and below the hexane has turned into crystals. I'm not really sure why but maybe the evaporating hexane was able to nucleate some seeds, dropping them in the oil layer, where they consumed the oil as they grew. The oil layer is totally gone now and there's 2 dozen crystals swimming at the boundary between the two solvents. It might just be table salt crystals that were formed from HCl + NaOH that mopped up the DMT oil.

Idk if it would work for vinegar, sodium carb, toluene, but thought I'd share those results.

Hi Icon, thanks for sharing your results. The visual also really helps to know wbat to expect.

But I think if you had put it in the fridge or freezer, the dmt oil would have hardened and you can just pick it up. I've done that before when collecting dmt goo off a dish and it really helps. And it sometimes changes it's crystaline structure such that it doesn't turn back to goo if you bring it all together.

This seems to be a much cleaner way to get dmt freebase, as there is no trace of solvent likely. It also seems to be more efficient than scraping a dish after evapping toluene and oxidising some dmt, or precipitating from naptha which has low pulling power, and is too selective for those interested in including dmt oxide and nmt.

Feel free to contradict me, I can be wrong.
 
True, if you can get it to float to the top into its own layer then you could skim it off. I like the freezer idea - if the oil doesn't harden, the water layer should at least freeze.
