Basically i extracted using limonene from a stb solution of root bark, then after a few 100 ml limo pulls , i added fumaric acid saturated water for, about 50 ml for a total of 4 times. Decanted the water after mixing it well with the limo and placed it in the freezer. Washed it with water after it was solid ice to take away the limo smell. Afterwards i melted it and evaporated it on a hot plate.
As far as i know the plate never reached temps greater than 80 Celcius. what i was left with was a hard crystal, smelling amost like freebase but not quite, hard as heck and amber in color. A bit sticky on the fingers too. Did i also pull something else or was there a mistake in my tech. The limo is left clear and with a light yellow color.

also , the product weights around 4 grams , from 250 grams of bark. I should also point that i have done STB before , only using naphta instead of Limo...i just love the idea of a reusable and non toxic solvent.

thanks in advance guys

A little bump and update. I did some more pulls on the Basified bark mix during this week and i tried to pull it out with FASIPA this time. The thing is that after 16 hours the solution is still cloudy and no separation seems to occur between the Limo and IPA.....what did i do wrong ?

Sounds like you did the right thing. FASW does pull a bit more waxy/impure stuff.. You can convert that to freebase as explained in BLAB, or if you wanted you could do cold-dry acetone/IPA wash, or do bufoman's water purification (https://wiki.dmt-nexus.me/FASA_Alteration_of_Final_Purification), or just consume as-is.

FASI will not separate in two layers, the crystals should precipitate straight out of the solution, as explained in BLAB. Add a bit more FASI to the mix to see if it gets cloudier, wait some days to precipitate. You can try putting it in the fridge too.. Once it precipitates, filter and wash them with cold-dry IPA or acetone to remove limo traces

Thanks for the reply man, i really appreciate it! One more question if you will : Is there any way to separate the IPA from the LIMO or are thy lost to me ?
