I have been following this tek for my first couple of extractions
https://wiki.dmt-nexus.m...Lime_A/B_Extraction_Tek

I have substituted the d-limonene for sunflower oil, and I'm using acrb but other than that I have followed it to a t.

I've had a few emulsion issues,(edit: I'm also using sodium carb, not lime because I believe the lime I used caused my emulsion problem) but that's besides the point.

One of the final steps is to vaporize off the acetate leaving freebase DMT. Can anyone attest to this? The final product im left with is a waxy light brown/red substance.

It's definitely active when smoked. But it has a sour, almost vinegary taste at first and I'm wondering if I'm simply burning off the acetate from the vinegar when smoking it either through my vg or on some bud.

I'm a little new to all this, and not a chemist by any means. After this batch I'll be switching to lye/naptha though because I found a good brand for both ha-ha.

Any help is appreciated

Yeah, the vinegar evaporation into freebase DMT is not 100% effective, in my experience. The vinegar never really seems to fully go away... You should look into the acetates conversion to freebase in the WIKI under the BLAB tek especially since you already have sodium carbonate. It is the very last step on that page.

Cool, thanks. Any other advice is always appreciated, I really wanted to stay with a food safe extraction method because I don't trust that everything in solvents evaps off, ha-ha call me paranoid.

If you've got 95% ethanol, that's as near to a food safe solvent as you'll get. Acetone is also pretty safe*, at least from a food point of view, and evaporates more easily.

*I'll add some acetone caveats before someone has a go at me:-

>Yes, it's much more flammable than EtOH, but that too would require sensible working as does naphtha - i.e. no naked flames or incandescent material in the vicinity.

>Don't drink acetone, it's neither nice nor good for you.

>Always carefully distil new acetone unless you're absolutely sure it's of pharmaceutical grade and free from additives.

Use citric acid instead. You'll find it at walmart near the pressure cookers.

I'll give that a try, thanks. I might as well go get some litmus paperto test the pH while I'm at it ha-ha.
