Nah, I didn't. Will try that.
Now after more than half a day, a tiny bit of fine powder precipped out. But the liquid is still mainly yellow. And what precipped out looks completely different than the stuff in his pics.
But I still don't get why on his pics there's no yellow at all???
Even on the pic with acetic acid, where he said, it just starts to precip out, there's no yellow. Why is there no yellow??? The liquid should be strongly yellow, at least as long as the stuff didn't completely precip out yet. I really cannot understand this. Anybody an explanation?
Also why is his citrate white? Isn't harmine citrate also yellowish?
Edit:
i disolved some harmine in water and a dash of lemon juice - added the same amount of acetone as water and noticed massive precipitation.
Hmm, I needed quite a lot of citric acid to dissolve the Harmine in water. As their molecular weights are almost the same, you would need at least as much citric acid as Harmine FB to get the citrate. So a dash of lemon juice seems a bit small to me.
Could it be that he actually didn't really dissolve the Harmine but basically just washed the FB in water and acetone? Hmm, but he explicitly wrote that the Harmine dissolved...
I really have no idea what to make of all of this. Anybody an explanation?
Edit2:
Hmm...Just had another idea. Harmine FB does dissolve a little bit in plain water. Maybe he did that? Then the water wouldn't get yellow, as the harmine remains FB. But you would need quite some amount of water for your amount of FB, which from his pictures doesn't really look like that. Or does really that much harmine dissolve in plain water.
This could then make sense. By adding the acetone, the acetone binds stronger to the water than the FB and the FB would again fall out. So the white stuff he gets out would actually already be FB and not citrat. Actually there would be no citrate.
But why then adding lemon juice?
BTW: What would happen if you would just wash the FB directly with pure acetone? Would it dissolve the FB? If yes, then IMHO the water acetone ratio could be extremely critical. If you have more water, some FB would stay in the water, if you would have more acetone, the FB would stay in there.
Edit3:
Ah saw in the Wiki that FB is quite soluble in acetone with 4mg/ml. So a direct acetone wash is not recommended. Unfortunately we have no numbers about the solubility of FB in water.
Maybe just a tiny bit of citric acid makes the water dissolve much more FB, but not enough acidity to create citrates.
So then my mistake would have been, that I thought the FB must be converted to the citrate, whereas one should only add as much citric acid, that no citrates are formed yet. No idea how much citric acid this is. Anyone a guess?
