I don't know what the fuck I did wrong. I preformed an A/B following Loki's tek on some acacia confusa (root bark) and all was going preeetttyy well until the end. I have my naphtha in the freezer at the moment to try my hand at one more freeze precip, but the first time I removed the casserole dish, I let it sit for too long and the nice pretty white crystals started to dissolve back into the naphtha. So I thought, "okay, my bad, should of removed the solvent faster." I recrystallize the alkaloid on low heat for a few and then stick it back in the freezer. Again, a nice field of white crystals was observed, though upon pouring the solvent off and scraping, the pretty white crystals would quickly "melt" into a tanish goo. To my understanding, naphtha is still trapped, bethat it be by plant oils or just solvate interactions. I have recrystallized and tried to freeze precipitate again, then evaporate the little remaining but with no avail.
So my question, I guess, is besides reduced pressure (working on getting a pump but do not own one at the moment), how can I obtain my precious alkaloid? Naphtha will not evaporate, unless I should leave it longer.
