non-polar-solvent

I tried a first A/B extraction and I'm waiting on the results, in the meantime I was wondering, since the "usual" solvents are kinda hard to come by where I'm from, would it be possible to do pulls with acetone instead of naphtha/hexane/whatever and then make the DMT drop as Fumarate by adding...

I have never extracted DMT before, and whenever I read TEKs, I find myself most hung-up on the evaporation step (if applicable). I wonder how to do it, practically. First of all, I wonder what temperature to have; though that would depend on the non-polar solvent used, so I guess I can just...
