So I've had around 50ml of naphtha sitting in a jar with a lid on it for a few weeks. The naphtha has some DMT in it as it consists of the leftover naphtha from a freeze precipitation. It has quit a bunch of floaters of DMT crystals that didn't stick to the pan and that I didn't catch when pouring off the solvent after freeze precipitation from two pulls. The quantity of DMT I don't know but I know there's a worthwhile amount in there. I digress though so let me get back to my point.

Originally the NPS was a slight yellow color. Now after sitting in this jar for a few weeks. There is quite a bunch of brownish oily things in the bottom of the jar. Today I placed it in a year bath and poured it into a pan to evaporate. After all the solution was transferred there's still a bunch of this oily stuff that was stuck to bottom of the jar that would not melt back into solution while in the heat bath. However all the little oily brown things are now in the pan evaporating with the NPS.

Does anyone know what this is ? I'm assuming it's either oils from the mhrb or its lye contamination combined with plant oils. Point being if I'm wrong and its active I done want to discard after it evaps and if its not active I don't want to mix when scraping with whatever DMT is present.

Dmt n-oxide is not soluble in solvents. Could be that.

iirc, not in naphta but in xylene yes.

Is DMT n-oxide present in large amounts in mimosa? Also that doesn't seem right as like j said its NPS I used to pull previously. It had nothing in it before as everything was dissolved before freeze precipitation. After sitting its appeared. Is DMT n oxide a product of degraded DMT?

I've let the solution evaporate and on one side of my pan the brownish oily is present and the other is where all the DMT stuck. Currently its very thick and slowly runs down pan like syrup. I'm waiting longer to see if it will crystallize as I'd rather not have oily stuff.
