The point of fasa is to precipitate DMT fumarate from acetone containing freebase dmt, in which freebase is abundantly soluble, but not the fumarate, and quite probably other salt forms of dmt. Which is why fasa works in the first place.
Now what you propose is to dissolve a SALT of dmt in acetone, and then add fasa to precipitate a SALT of dmt.
Theres a few problems i can see, not that i may/may not work, you should try and let us know how it works btw.
The first is that we don't know what dmt salts naturally occur in the plants we use to extract (often time different species with different alkaloids, and perhaps different salts).
And as such we cannot determine if they are even soluble in acetone as a salt. Since acetone is used to wash/clean up dmt fumarate (ie it does not dissolve it), i would assume other salts of dmt would be sparingly soluble in acetone as best.
IE natural dmt salts may not even be soluble in acetone, and obviously that means this proposal would not were if that is true.
The second problem i see, is assuming those unknown natural dmt salts are soluble in acetone, will they disassociate from their ion (the acid used to make that dmt molecule a salt), or is the bond between the dmt and that acid stronger than the bond that would form with fumaric acid?
If so, nothing would precipitate, since the dmt is still in solution as the tannate, or whatever numerous natural plant acids it could be forming a salt with.
Like i said, these are just theoretical problems with your proposed idea, and if you test it and it works then i would be glad to be proven wrong, because, well, that's a pretty simple and easy tek you outlined IF it works.
Just my 2c
Very curious to see how it turns out if you do decide to try it though :thumb_up:
