Almost no and 'fatty' residue

Hi,

I tried my first pull and the results were not so good. I obtained only very little dmt which was quite 'wet' or fatty emulsion, which didn't really dry out after.

Steps:
100gr jurema root bark shredded
Moisturized, added half cup vinegar and 2 cups water
Boiled for 3 hours
Added some more water and vinegar during cooking to increase volume
Siphoned off the fluid into glass jar
Added NaOh 80gr/L to fluid until solution turned black
Added around 100ml naphta per pull
Pipetted naphta from top of solution after around 3 hours and froze overnight in glass lunch box with lid on.
Poured off naphta and let residue dry... around half a day.

Result: only the first pull showed something, however very little, just a small dot, and it was not dry powder at all. It seemed to remain wet from the naphta.

What am I doing wrong?

Thanks for any suggestions.

I hope to improve soon.

Yes, the 10g of acetic acid (assuming a vinegar at standard 5% w/v) would require (10/60)*40g = about 7g NaOH to neutralise. The remaining 13g likely won't have been enough to react with all the bark tannins, etc.

Thanks! this was an extraction from another naphta that was too heavy. So no bark. It was a "back salt ".

What is the pH? Over 11 would be high enough.

Or maybe there actually wasn't any dmt in the nafta. Did you notice any white cloudy precipitation when adding NaOH to the vinegar solution?

Ah, OK - in which case, you should have got something, if it was there in the first place. I'd try salting the heavy naphtha one more time using dilute HCl, just in case aromatics content has held on to the DMT acetate somehow.

DMT would still freeze-precipitate, ime, from heavy aliphatic naphtha as long as it's relatively free from aromatics. We kind of need to establish whether there's even any DMT present at this point.

It would pay to evaporate down a sample of the vinegar pulls using a bain marie.

Thanks for the elaborate reply. Unfortunately I already tossed the remaining vinegar. I ended up with a few mg I think, so indeed the very heavy naphta may be another reason.

Well lesson learned in any case.

Yes i think the solution was quite cloudy but it could be the vinegar shaking

Was that cloudiness with or without added naphtha?

It's true that adding NaOH could cause clouding through bubble formation from localised heating, so you have to observe very carefully for a little while to be sure of what's going on. Bubbles will float to the surface and dissipate, whereas DMT would float up more slowly and form an oily layer or even small masses of solid.
