Hi,

I made a nice batch of changa but destroyed it with denaturized ethanol at the end.

I checked the forum on this question but could only find not clear answers on the case where someone used acetone.

So....my question is, can I re-extract the dmt from the changa without getting the nasty denatured-add-ins from the ethanol?

Thank you all!

I doubt anyone can answer this question without knowing what was used to denature the ethanol. If it was only denatured by addition of a volatile solvent (methanol, isopropanol, acetone etc.) the changa might be fine once it is evaporated fully. Bitterants might be a bit more tricky.

Yes....i guess they added bitterants. Because if i vap the ethanol on clean table fully and lick after evaporation on it, it still taste bitter.

So....still the question if these bitterants come into the naphta by a new extraction of the DMT out of the changa?

The bitterant should be of minimal solubility in naphtha although it potentially will have phase-transfer or surfactant properties so beware of emulsions. Once you've pulled into naphtha and obtained freebase crystals, you'll likely want to recrystallise the DMT from fresh naphtha, or perhaps repeat the A/B extraction procedure just to be sure. Bitrex is pretty powerful stuff, truly minuscule quantities are still detectable to taste.
