SADLY, i don't have any answers on the matter for you....but i will piggy-back this querry of yours in the hopes that when jorkest, acolon_5, 69ron, infundibulum, burnt,psychosisdoses, et al finally make it here they can give us a nice broad enlightening on this whole fumarate process.
....you see...i just did my first fumarate extraction...
i used hot d-limonene and pulled from a pretty exhausted (or so i though) basified soup. 2 x 400ml....let it sit for 5 days, shaking vigorously every day for every bit of spice to crash out. in the end i'm looking at almost 2 grams of lemony-fresh fumarate crystals (a very pale yellow color).
NOW- aside from absolutely wanting to know the answer to mmm's question about cleaning excess fumaric acid off, i would also like to know what i should do with this 800-ish ml of FASI-saturated d-Limo? is there any way i can "clean" it to be reused or, at the very least, reused to clean my home? i absolutely refuse to think that i have to throw this out....
come on my well-chemistry-endowed friends- give my sister and i a fumarate schooling!
MUCH LOVE AND GRATITUDE!!
