IPA za kristalizacijo 4-mmc je slab. Metanol je najboljši

To je mogoče. 1 g 4mmc na 0,7 ml vode pri vrenju. Nato le pustite na hladnem mestu za 10-12 ur

Im je narejen z ipa in narejen tako, kot vidiš, da si naredil 3 tedne, ker uporabljaš preveč vode enostavno

Kako čistite prosto bazo? Samo z vodo ali tudi z NaOH ali raztopino natrijevega bisulfita?
Kako dolgo kuhate DCM z 2b4m in pri kateri temperaturi?

po reakciji 2b4m z metilaminom v DCM prosto bazo mefedrona 2-3-krat speremo z enako količino vode. reakcija z metilaminom traja 4 ure pri temperaturi 32-36 C. DXM ne spravite do vrenja (38 C), saj DHM pri vrenju hidrolizira, prosta baza bo močno onesnažena. če upoštevate temperaturo/čas, bo prosta baza zelo čista.
