So my friends run yielded a dismal amount that ended up being inactive, probably through his error.
This time he is thinking of using a wider container to increase contact of the mixture to the solvent, as well as using slightly longer solvent soaks as well as using more solvent. He is also thinking of decanting and filtering into a wider container for salting, which would allow him to then decant the solvent and air dry. Afterwards he would scrape up the crystals for washing, allowing him to avoid the filter loss that occurred in his last extraction.
He would also like to know if the fumarates could be dissolved and water and freebased by adding surfactant free ammonia while stirring, later collecting the freebase from the glass stirrer as described in another well know purification thread on another well known forum that provided fantastic results for that specic alkaloid?
Any thoughts on these considered improvements?
UPDATE: Well my friend used the last of his bark doing a scaled up version of the original run he did, this time with more care taken, only to end up with very minor precipitation when salting the acetone. His bark must either be bunk or something, it fails to reproduce the same or similar results every time he pulls it and so far has only yield miniscule, inconsistent amounts.
Any thoughts from the more experienced out there? He has successfully extracted other alkaloids from other plants and is no stranger to purification and basic extractio but can't figure out what the hell is up with this stuff.
