I want to convert DMT base to DMT fumarate but I just dont get it- there are so many different teks

[eljapoppo56]

Hey yall, hope youre having a good night.

I have freebase that I extracted from MHRB using vinegar, NaOH and heptane.

I want to convert this to fumarate but so many teks use different solvents and it confuses me.

I've been extracting freebase for years and always thought A/B was superior. I hsvren'y logged in here in a while and it seems there are better new teks with better results and experiments (FASA/FASI).

Anyways, can anyone lay this out for me like a total noob? What is the most current best tek for converting base xtals to fumarate?

I tried anhydrous acetone with 601mg(?) fumaric acid in 50ml and mixed with 1g freebase DMT in 50mL and there was instant precipitation (this is the easiest seeming tek). I let the solution cool in the freezer and the xtals floated to the bottom and required some intense scraping to free them. I then filtered the precipitate and washed with cold anhydrous acetone. The product is a yellow color powder and not oily. I haven't weighed it yet cuz I wanna do more acetone washes. Will the acetone washes even wash away the excess acid?

I'm sorry for the noob questions. I can get naptha, heptane, ISO or ethanol, methamol, MEK, and limonene. I'm not sure if I can get xylene. Anybody willing to help a homie out?

Thank you!!!

You can do a fumaric acid saturated Isopropanol and stick your freebase there.

The amount required to neutralise 1g of base is 616.5 309mg - which, amazingly enough, is the amount of fumaric acid that will dissolve in 50mL acetone.

If the acetone is slightly damp (it's hygroscopic...) you'll risk washing away some of the fumarate.

(Edited cos I forgot that 2 moles DMT react with 1 mole fumaric acid )

Thank you!!! Does the ISO need to be anhydrous as well? If so, can I dry it using MgSO4 like drying acetone?

Thank you!! I couldn't remember the amt of fumarate off the top of my head so I guessed, but i did use 309mg

Thanks again! Also sorry this isn't a "reply" I'm on mobile and don't see a reply button anywhere, just a "quote" button
