Sorry to dig up an old thread.. this is the only info I can find on freeze precip with acetone.
I am attempting to crystalize an Acacia floribunda extract.. this species is notoriously difficult to obtain a solid extract from. It is usually an amber/yellow oil/toffee texture.
I have been attempting to precipitate DMT from acetone .. at first it looked very promising. I dissolved my alkaloids in a small jar. The acetone took on a deep red colour.
After about half an hour in the freezer, cream coloured precipitate was noticed floating in the solution. I filtered the solids onto a coffee filter and dried them. They ended up a “putty” like texture and were a dark brown when scraped up.
The precipitate is far less sticky than the usual difficult to handle extract but it seems the majority of the DMT remained dissolved.
I’m not at all bothered if the extract crystallizes - my hope is to at least get it to a point where it can be dried and scraped up. It’s difficult to store otherwise. Whatever the really sticky stuff is, it’s still highly soluble in cold acetone which is encouraging.
I then evaporated the acetone in a separate dish, which yielded what seemed to be the bulk of the extract still.. again, an amber oily consistency. Both the precipitate and the evaporated acetone are highly active.
@benzyme .. is there a certain level of saturation required with acetone to drop all of the alkaloids out when freeze precipitating?
This seems like a potentially good way to tidy up Acacia floribunda extract. But the precipitates were a fraction of the total extract.
Any advice would be greatly appreciated.
