Swim was thinking a bit about the fasa tek again and was wondering if this sounds feasible-
mix mhrb and calcium hydroxide and a lil water as with the other dryteks
pull with acetone - then after separating add fasa to the pull acetone - if there is a problem with the mixed solution not containing enough fumaric acid more fumaric acid can be added - excess shouldn't be a problem because the product is to be freebased anyway.
im sure xylene could be used but i asked this question with acetone because it evaps fast and doesnt stink like xylene.
