About to precipitate some mescaline salt out using anhydrous acid saturated acetone. I may do HCl because I haven't the slightest clue where my wee bottle of fumaric acid got off to. Narmz in another thread reported that using fumaric acid takes days to precipitate from d-limonene, is the same true for xylene? Has anyone left it around for an extra while to see if anything came out?
But my primary question involves xylene. According to Tregar at mycotopia Xylene holds 1-2 ml of water per liter. He also says that very small amount will cause the salting (done by HCl gassing) to produce dirty crystals whereas using it dried will cause much cleaner crystals to precipitate. Is it at all necessary or important to dry the xylene before salting? Or does it just cause an extra cleaning step? Or no perceptible change at all?
Has anyone done tests to see how soluble various salts are in water? When using say 2400 ml of xylene the only loss would be to the to 2.5-5 ml of water and not interfere with the salting in any other way? This guy references a paper claiming freebase mescaline is soluble in water at 84.1mg/ml -- the wiki entry says freebase is "moderately soluble" while a number of the salts are just "soluble", which I imagine means more than moderately? So is there significant loss (>85-170 mg per liter of xylene) here? Can anyone with some salted mescaline do room temp water solubility tests?
Vaguely related question: anybody have a rough idea how much 30% HCl solution is sufficient to salt out alkaloids from 250g of fairly potent cactus? Sorry for all the questions!
