Ali je mogoče amfetamin freebase destilirati v vakuumu brez dodajanja vode kot pri običajni destilaciji s paro?
Če je odgovor pritrdilen, ali je to mogoče v rotovapu in pri kateri temperaturi je temperatura vrelišča, na primer pri vakuumu 100 mbar? Ali kdo ve?

Ta snov postane hlapna z vodo in za destilacijo ne potrebuje visoke temperature.

To vem, vendar sem slišal, da je destilacija hitrejša, če jo opravimo v vakuumu, v tem primeru z vodo, ali to drži?

Da, lahko poskusite. Uporabite vodno zapornico na vakuumski cevi in tako rešite vakuumsko črpalko.

ljudje pravijo, da lahko prosto bazo ekstrahiramo z dcm ali z uporabo parne destilacije .
Če se odločim za drugo možnost, ali moram snovi najprej dodati vodo ?

Brez amfetaminske baze je prozorna ali ima rumen odtenek. Ali ste kuhali prosto bazo s HCl in je vaša raztopina proste baze amfetamina postala črna? Verjetno ste izdelek preveč oksidirali in se je pokvaril.

Ali lahko natančno razložite postopek, ki ga želite opraviti, prosim. Še vedno ne razumem popolnoma, kaj želite narediti. Ali želite destilirati prosto bazo amfina neposredno iz reakcijske mase po sintezi amfina?
