A necessary clean up from a mistake has led astray from Fumarate to FB. The final step needs to go back to the Fumarate.

Any ideas?

Sorry if it is here somewhere I will do some searching...

The only way they can think of is Redissolve in High Purity Limonene and Salt out again.

You can dissolve in Acetone and mix with FASA or dissolve in IPA and mix with FASI.

Actually my brain is scrabbled I guess. Endless had been working on this project here:

Anyway I guess what confused me is the idea of just adding FASI to FB saturated IPA.

Never heard of that done; it's like I can not wrap my head around the idea of not needing the Limonene in this process.

So basically I dissolve FB in IPA then add FASI.
IT is that simple huh:

Plumsmooth, I don't see the need either to pull your FB with solvent such as limonene, as it has been said, you can simply turn FB into salt by dissolving it and then salting it, it is as simple as that indeed.
So the suggestion makes sense (dissolve FB in IPA and mix with FASI).

I got it so in that sense the little but of unsaturated IPA that you use to dissolve the FB will not effect the proportion such that one will lose any Fumarates...
