So, after pretty busy days SWIM finally found some time to go back to an old Project he was working on..

It's about cleaning Fumarates and now he stumbled over the 10 min Conversion TEK, which might be a solution for him..

So, SWIM had some Fumarates with quite an excess of Fumaric Acid, he wanted to get rid of…


Then he did a try with Water-Chrystallization as described here
https://wiki.dmt-nexus.m...n_of_Final_Purification, but it turned just into a waxy yellow brownish goo, which became pretty hard after a while.. but resulted in the following:
..

so the Excess of Fumaric Acid should be washed out, but it looks terrible as this brown hard Fumarate clumps..

He aslo tried the IPA conversionTEK, but the result was not as clean as expected, . Outcome was a whitish powdery product which doesnt really look very clean. (but still fumarates)
see here:


As SWIM still has left like 3 gr of the brownish hard Fumarates left he decided to give the :10 min TEK a chance and convert to freebase as described here, as the starting point of the Fumarate looks pretty similar to the Fumarate he has..

Would maybe this way the solution to get a useable outcome-product

He would be pretty thankful for any advice on this…


cheers
