ChemisTryptaMan said:Hey guys, been a while since I've been on here and just decided to check in. Someone asked about using xylene for the defat. Very bad idea. The problem here is that spice is soluble to some extent in every solvent in both of its forms. Spice is also an indole which means it is aromatic. This will cause both it's forms to be highly soluble in xylene and toluene, which are both aromatic.
I think some variation of this tek can expose the real potential behind acacia. I believe it to be a very potent source, but the defat step has to be perfected. This has to be done with a solvent that is great at picking up oils but one that does not like the protonated spice. I would think gamsol would be a good one but you never know for sure. I think an alternative route is just to pull everything and then worry about seperation techniques once all the spice is freed from solution. I've been playing with DCM as a cleanup solvent with some success, but I'm finding the best results are coming from my hybrid solvents that incorporate aliphatics and DCM. I plan to keep working on this and will let cyb know what I find. Happy extracting nexians!

Thanks for that ChemisTryptaMan, I'll keep the xylene for just my later pulls
