Great to hear of experimental results, even failures and difficulties. The poor solubility of ascorbic acid in EA is rather predictable given its high proportion of polar oxygen atoms. This may help with crystallisation since it makes it likely that the M ascorbate will be a hydrate, so moist EA may be advantageous in this situation (fingers crossed on that!)I thought it might be interesting to try CIELO with ascorbic acid, so I tried a rough solubility test with EtAc and the result was much worse than citric acid. I used L-ascorbic acid 100% food grade, roughly 10mL dry pure EtAc, and ~55mg ascorbic acid, but it would not dissolve. I was shooting for the CIELO equivalent 5g/L proportion like the tek roughly is currently. Perhaps some dissolved but a lot did not. I tried heat for awhile >55C but didn't help. Added 0.1mL distilled water at a time, shaking, returning to heat awhile, shaking and checking, and ultimately ended at 0.4mL (4% of EtAc volume) before it fully dissolved. It didn't precipitate any out after chilling a bit and left at room temp, so maybe I could have done 0.05mL water increments and ended at 0.35mL with some precipitating out after cooling.
I think I'll try a 2.5g/L proportion with ascorbic acid in a CIELO tiny batch. I assume that will be OK with the typical water content in the CIELO extract and given however much ascorbic acid will be consumed by the mescaline ascorbate crashing.
Looking forward to hearing how it goes since this is something I specifically didn't bother with on account of that poor solubility.
