SWIM had about 38g of MDMA powder after completing gassing. SWIM took this 38g of powder, dissolved it in a minimal amount of boiling IPA (91% IPA dried 3x MgSO4). This was let to cool to room temp, and a healthy amount of dried acetone was added. This mix was then placed in an air tight container, and kept in the freezer overnight. After filtration, only 16g of powder remained! SWIM is planning on boiling down the IPA/acetone mix to recover as much of that crystal as possible, and then peform another recrystallization.
SWIM is curious if anybody has any idea why the hell he lost so much product? He has been very careful to follow all directions closely, A/B washes and whatnot, and has a hard time believing that there was 20g of crap mixed in with just a tiny amount of X. SWIM had used 36g of MDP2P, so he was expecting a much higher yield. He has done other reactions with appropriate pre-crstallization yields, but has always lost more than he though was correct during recrystallization... but this >%50 loss is bullshit!!
Any suggestions on different methods would be highly appreciated.
Thanks
