Orcjidist, I used whole cactus powder earlie on and got xtals. However, there could be difference s in drying, cactus, etc.
Have you always gotten goo using citric acid with the other whole cactus powders?
Anyone else get xtals with whole cactus powder? If yes, how did they dry it?
Anyone get goo with outer skin after feeling they got the process done right?
Unfortunately, I have no way to be sure of how these powders were prepared. Wish I did.
I still have one more powder to try, just looking at the paste, it's definitely a different cactus than the others--using the same ingredient proportions as prior runs, this one mixed up to a tough, rubbery consistency, and stuck to the spatula aggressively as I mixed. Really made my arm hurt. Not sure if more water will fix it, but at the risk of introducing more variables than I can deal with, I'm going to carry on with the next steps, hoping it'll loosen up when the EA is introduced.
For comparison to any others who may report back on results with whole cactus powder and drying, I've been using Na2CO3. I may not have allowed it enough time to completely dry the solvent, so I can try leaving it for longer, or switching to K2CO3 if Na2CO3 isn't a good substitute for it. I also have molecular sieves now, so I could try that out as well.
I do see the benefit of drying, even if my procedure resulted in incomplete drying. With fumaric acid, the extra step gave bigger crystals than when I left it out.
It does seem that what I'm observing with citric acid is consistent with the formation of a biphasic system and ultimately a mixture of acid and salt like Nemoo described. With the addition of CA, my solvent partitions into layers, and the oil forms in the lower layer, almost exclusively near to where crystals of solid CA were present. Adding a quantity of CA calculated to be slightly in excess of the yields I got from my successful run with fumaric acid also produced oil, in that case, the oil formed exclusively around where the pile of citric acid had been before it dissolved.
I'll put extra effort into improving my drying process and give dissolved citric acid a try as well. Thanks Nemoo for the suggestions
