Swim has a question for yall:

Can you freeze precipitate Xylene or Toluene pulls ?

Since it would save a bunch of time ,instead of having to salt your limo ;then freebase it...........

Nope. DMT is too soluble in them even at your freezer's temperature. Same with limonene...

I moved this to the general extractions help forum because its not really advanced chem, and edited the thread title to help others who have the same question to notice the thread

Thank you ,by the way, for all of you who ever wondered if naphta and limo mixed together will separate ,the answer is no.

That would be a resounding no. Salt it out of your solvent, or be patient and evap.

Well since dimitri stays in the xylene while freezing, and not having a separation funnel, I used cold as a physical separation tec, just pooring of the xylene while the base-tea stick in the bottle. Thaw the bottle for next pull. It takes some time indeed, no big deal, it gets the job done.

Not sure, but it seemed that when freezed, the xylene had some less red tan, compared to before the freeze. If really so, it like a purification embedded.

(Dont mind the amounts used, it was a test case.)

the color change is probably the less soluble oils in the cold temperature


as far as freezing between each pull, its a novel and useful idea. however for efficiency simply pour off 80% of your pull and add fresh solvent, then pour off 80%, its ok if you get some base in your nps collection vessel because you can pour off the clear solvent after all pulls were completed. let your collection vessel sit to allow microscopic aqueous phase collect at the bottom and as such they wont interfere with your salting process (ie neutralizing your acid)


looks like your using some ingenuity, kudos to that
