SWIM's first STB MHRB extraction

Steve_B · 10-03-09, 13:05

SWIM recently performed a STB tek from 50g of MHRB with 4 naptha pulls wo/ freeze precip. Just evapping all naptha in a pyrex dish and was left with some nice yellow crystals, SWIM dosen't have scales accurate enough to weigh it, but SWIM will work something out and try to find the weight.

If SWIM did do a warm naptha freeze precip, what would the losses be? Considering it's only from 50g MHRB.

Get a taste before you decide to wash anything.

I would also hive it a try first. such a small amount you might loose too much.

If you wanted to play around with it, you could do a room temp heptane wash.
Evaporate the heptane for shards and save the rest (which will still contain a lot of DMT) for jungley goodness.

Shouldn't lose any yield from freeze precipitation, as cold naphtha (or preferably heptane) holds very little, if any DMT.

The naphtha used could be any number of mixes however, so one would want to be sure to use certain naphtha mixes, for freeze precipitating. Naphtha can be any number of petroleum distillate mixtures, and some will not precipitate the DMT as well, and why heptane is preferable for recrystallization. Heptane holds DMT when hot or warm, but will not hold it when at freezing temperatures, which is why it works so well. Hexane holds more DMT, but doesn't freeze precip as well, and is often one of the chemicals mixed in with naphtha.

Still, most brands of VM&P Naphtha, will not hold much DMT when at freezing temps, so loss in yield would be very minimal, if at all. The yield wouldn't be lost, either, as the solvent could still be evaporated to yield whatever didn't come out in the freeze. SWIM thinks you'd be surprised at how little DMT can be held in most VM&P naphtha at freezing temps.

EDIT: Be sure to use as little of the very hot solvent as needed to just dissolve all the DMT, to keep any possible loss very minimal. If the naphtha holds a little DMT, then using only what is needed to just dissolve it all while really hot, will ensure very little, if any, is held in the freezing solvent.

I agree, add to warm naptha and re-freeze precip. even such a small amount can be helped. SWIM has done this before with only 100ish mg of spice. GL!

Thanks guys, SWIM will look around for some bestine to freeze precip. (anyone know any sellers in the UK?). If not, SWIM will just freeze precip with naptha, then evap to see if i lost any.

P.S. SWIM got a yield of 1g yellow powder, which seems too high...

SWIM just freeze precip.ed and got a pure white powder (still drying, SWIM will report with weight later)

But SWIM has some leftover yellow gunk from the freeze precip after having disolved all in hot naptha. Is this any good?
