So if you are left with your chilled and evaporated Acetone pulls and you dissolve them in a minimal amount of IPA, then just add 2x the volume of Naphtha afterwards and place it in fridge, then after 5 min the grey voluminous clouds will have separated and settled even stronger, so you can speed up the process and also decant them much easier. With only that minimal amount of IPA it may be a little messy, but increasing the volume when its supposed to precipitate may make things much easier.
Thanks Brennendes Wasser, I tried this out. I added naphtha to the used frezer re-X IPA and more stuff crashed, resulting in 65mg of very white powder. In my case it helped recover yields, perhaps I used too much IPA for re-X originally (I used ~ 50ml, which should only carry 30ml of salvinorin at room temp). The 65mg is more than I expected, maybe the plant stuff helps salvinorin dissolve in cold IPA (?) or maybe the product is not all salvinorin. Originally I let it crash for over a week, so it should have finished the IPA re-X before I added naphtha.
Overall, I think naphtha does make re-X easier and more robust. Also, it can be used to rinse off any traces of green IPA wich helps remove the small off-color to leave a white product that looks very nice.
The naphtha use brings the total yield up to 180mg for 85g of dry leaves, a respectable 2.1mg/g (assuming the powder is mostly salvinorin), but not at the level that gibran2 got with the washing approach on his leaves.
Next year, I'll do this again with my grow:
3x pulls (60s shaking) with(-15C) acetone pulls of dry leaves. Evap and pickup green powdery residue with boiling IPA. Add 2x volumes of naptha and crash in freezer over a few days. Decant and immediately wash with naptha to help remove traces of green solvent, finally dissolve in acetone and dry slowly in flat dish away from light. The result is a beautiful white xtaline powder, I'll report back with the bioassay someday.
Cheers.
