Hey, this is my first post here on this great site. I've been reading other's posts on and off over the years as the right time for me to finally try DMT has come closer and closer. It's my experience working with ACRB that has me finally making a post of my own. Due to restrictions placed on the sales of MHRB, many (including myself) have been forced to work with Acacia. I'll admit, I don't read many of the teks as I much prefer to use my own knowledge to work through extractions and solve problems on my own. It makes the chemistry much more enjoyable than following a cookbook/recipe type of method (atleast for myself).
It wasn't until all the (rather frustrating) problems I kept running into with regards to ACRB that I finally resorted to reading some teks. It turns out others had had a lot of the same problems I was having. The problem is, no matter what tek I tried, I couldn't attain reproducible results, and based on posts from other users, it seemed to be 50/50 as to whether other forum members could repeat the results of the poster as well. Some (including myself) would end up with crystals, some with goo, others with something else entirely, even when performing the same procedure on the same plant material. Granted, the goo is just as psychoactive as the crystals, but it makes it hard to accurately gauge doses.
I sincerely apologize if I'm not the first person to devise of such a method, or if a similar procedure is already out there somewhere. I don't have time to look through and read every tek. I'm just putting my findings out there in the small chance that it'll help atleast one person. In my own experience, this is the only way I have ever been able to consistently and reliably free my product of any yellow tint or goo. I made sure to test it on various sources of plant material as well, so I know it's repeatable.
Procedure:
100 g of appropriate plant foliage (that had been frozen and thawed three times) was suspended in a solution of 60 mL 5% HC2H3O2 (vinegar) in 540 mL H2O, brought to a vigorous reflux, and held for 2 hours. The mixture was allowed to cool before being washed with 2 x 125 mL dimethylbenzene, treated with 60 g NaOH, extracted with 3 x 125 mL naphtha, and the solvent distilled off, leaving behind the crude product as a yellow oil that changed to an amorphous mass upon cooling. This residue was dissolved in a minimum amount of dimethylbenzene and thrice shaken with an equal volume of dilute (~pH 4) HC2H3O2. Any residual organic layer was removed, and the aqueous layers were pooled and treated with 10% of its volume (in mL) in grams of NaOH to bring the pH to ~14. With the tryptamine back in its freebase form it was extracted with 3 appropriately sized volumes of naphtha, washed with H2O, the solvent distilled off, and the residual oil cooled to 0 C leaving behind a white crystalline solid that, upon collection, melted over the course of 20 minutes then hardened to a white solid with a waxy consistency over the course of 24-48 hours to give 1.376 g of n,n-dimethyltryptamine (1.376% yield) with the distinctive semi-sweet smell of new shoes/clothes. The product was free of any stubborn yellow residuals and seemed to be (qualitatively) mostly free of NMT
Many people have expressed displeasure with ACRB as a source of DMT, including myself. No matter what I did, I could not attain consistent, reproducible results with respectable yields. The product would either come out as yellow goo, or brown sludge, or any other type of amorphous junk. It wasn't until I sat down in my own time and did some significant tinkering that I feel I finally managed to solve the problem and create a procedure that should be reproducible for ANYONE looking to extract from Acacia. The problem was that a simple washing/defat of the original suspension would never be enough, and in my own experience, DMT attained in this matter seems to be inescapably tainted with yellow/brown goo. As a result, it was very difficult to crystallize DMT without also crystallizing the impurities. Getting a pure product that will solidify requires juggling the DMT between it's salt and freebase form between polar and nonpolar solvents in order to free it of any residual amber oil. Taking the extract from the suspension, reprotonating the amine, washing, then returning the amine to it's freebase and extracting completely removes the stubborn yellow tint and allows for the product to solidify. Another point of interest with ACRB extracts is crystal formation. I see a lot of teks suggesting freeze precipitation. The problem is, there will always be significant product left in the solvent, since there's no way to know how saturated it is. Since this is just a simple acid/base extraction of plant material rather than a reaction workup, the solvent can simply be removed and the product used as is. The only point of concern for contamination is NaOH, and it's insolubility in nonpolar organic solvent coupled with a water wash will guarantee none will be left after evaporation. The weird thing about Acacia extractions is that the cooled crystals always seem to melt, regardless of what you do. After evaporation of the final pooled extracts, the product will be left hot and in oil form which can then be cooled to a crystalline solid, allowed to melt, then smeared along a large surface area (wax paper works well if no flat pyrex dish is available), and allowed to solidify over the next 1-2 days before being scraped off. The product is very pure (according to M.P.) and the yields seem very high (and more importantly, very reproducible). Ontop of that I suspect I threw out a large amount of DMT and that if you wanted to be really anal and perform more extractions, the yield can be even higher.
