Menim, da je 300 ml DCM dovolj za to količino BK4, 500 ml je po mojem mnenju preveč in namesto tega bi lahko prihranili denar.

Kako dolgo traja vaša kristalizacija?

Upam, da ste v redu.

Kako tako hitro dobite kristale?

Ali imate v mislih kristalizacijo v hladilniku?

Hej, fantje, pred kristalizacijo sem imel raztopino rahlo rožnate/oranžne barve. Zdaj so kristali prav tako rahlo oranžni. Kako dejansko deluje čiščenje z drugo kristalizacijo? Umazanija ne izhlapi... Ali ?
Edit: delal sem z DCM..

Pozdravljeni ! Potrebujem pomoč.
Težava je v tem, da nisem pravilno sledil korakom, vendar sem dobil nekaj iz tega. upam, da bomo to lahko popravili...
Dodal sem tekočino 2b4m - 200 ml + dcm 200 ml + metilamin 40% 400 ml.

  1. Dodal sem tekočino 2b4m - 200 ml + dcm 200 ml + metilamin 40% 400 ml.
  2. Raztopino sem mešal 2 uri in jo hladil v vodni kopeli, da se ne bi pregrela. temperatura je bila 30-40. Nenehno sem preverjala temperaturo.
  3. Po 2-2,5 urah reakcije sem izvedel zakisanje in odstranil zgornjo plast.

4. Sušil/izparil sem ga v pečici pri 40-50 stopinjah Celzija, dokler nisem dobil belega prahu, kot je prikazano v prilogah

Poskusil sem vrsto in dal nekaj vzorcev: Zagotovo ima nekaj stimulativnega učinka, vendar tako močno peče v nosu, da je popolna katastrofa.
V primerjavi z običajnim MEF je zelo šibek.

Fantje, ali lahko popravim ali dokončam ta prah, da bi naredil nekaj bolj podobnega mefedronu?
thx
