Hi guys! Today something strange happened to me. I aminated some mdp2p with methylamine, then i did an a/b. When basifying, a lot of brownish raw freebase settled to the bottom of my sepfunnel. Weight was 96g of 'raw base', which i collected with 250ml dcm. The dcm was very dark. Then i stripped off the dcm and water as usual. Then i continued heating under vacuum to get my mdma-freebase out of this dark shit. But i got just about 20g clean freebase, very bad and i can not understand it. When basifying there was so much base (was it base?), what is the rest in my distilling flask? Are there other things which might separate during basifying?
PS: I was nearly running out of naoh, so i used koh to wash the toluene (after al/hg extraction), instead of naoh, which i kept for basifying after a/b.
