Singular Room Temperature Pull

[gatezz]

Instead of doing multiple pulls, what are your thoughts on instead using an excess of NPS to extract all the DMT in one pull and then reducing the excess solvent to saturate it? Also curious of everyone's thoughts on doing a room temperature pull to reduce the amount of impurities in the extraction.

If you use a solvent like toluene, theoretically one pull should suffice if you manage to separate all the toluene from the basic soup. In practice though some amount may remain in the mixture and therefore a second pull will be more efficient than the total volume of both pulls combined in a single pull.

If using naphtha and want to freeze precip, you have to reduce till saturation, but I wouldn't feel good about about reducing a large volume of naphtha: It's a fire hazard, unhealthy, bad for the environment and wasteful. Unless you have a distillation setup, I wouldn't do it.

With regard to impurities, I think there will be MORE impurities if using more solvent and reducing that solvent.

Somebody did the sums for this and posted it in its own thread. Searching is the answer.
One sensibly sized pull will get most of the goods. A bit warmer than room temp is better for that.

If you absolutely must, with a large pull the alkaloid can be concentrated by backsalting into vinegar, etc., etc.
