I want to perfect dmt crystals with almost no impurities.

I want to perfect dmt crystals with almost no impurities.
I am using the STB method to produce dmt using acacia confusa. So far, I have been reading the dmt Nexus site and books and putting what I have learned into practice.
I have been recrystallising dmt so far. I am looking for other methods to produce dmt crystals with almost no impurities.
I found sodium carbonate washing and acetone washing. Can anyone teach me how to do these two methods? Or is there a way to completely eliminate impurities?

A. confusa often contains NMT (the monomethylated homologue) which can sometimes make crystallisation trickier. @CaptainFuture made a thread about crystals a long time back, and @AbsolutelyPureDMT may or may not have had something to their username, so check out their posts.

You seem to have misunderstood something about acetone, you would be better off recrystallising slowly from heptane with a prolonged and gentle decrease of temperature, followed by a few cycles of Ostwald ripening if it's really large and pure crystals that you want. After that, redissolve them in ultrapure heptane and grow from a seed crystal by very slow evaporation.

Is heptane still the best choice for extraction when recrystallizing?
How would you rate hexane among non-polar solvents?

Hexane is a good solvent for re-x in being a poor solvent for DMT at room temperature and hardly dissolving any at all at freezer temperatures.

Its disadvantages are its having a lower boiling point than heptane, which can be inconvenient during warm extractions (leading to rapid evaporation) not to mention a rather greater flammability hazard. You'd kind of want to warm hexane up a bit for it to dissolve a decent amout of DMT.

The most important disadvantage is hexane's neurotoxicity, something that should be strongly emphasised. Because of this, the amount of hexane is strictly limited (<5%) in solvents that are available to the general public.

If you want real pure do a mini A/B aka backsalt on your extract. I always get white fluffy crystals from this.
