Example of Methamphetamine Isomers Separation

[Sjeik]

See peab olema selline...

Does using a larger amount of water so that the mixture does not turn into a paste affect the solubility of the L-Meth-tartrate salt?

Because it's almost impossible to work with the vacuum filter when it's like a paste.

Maybe I should add freebase slowly to avoid amorphous paste solid?

Soovitan külmutuskappi. Sel juhul mida külmem, seda parem. Temperatuure ei ole kunagi mõõdetud, ma säilitan oma metanooli alati sügavkülmikus.

-Polaarsus (polarimeetriga testitud) pärast ühte läbimist

- H20 (68-73% d)

- Metanool (71-76% d)

- Rusznaki protsess, tolueen kui benseeni asendaja (ikkagi ebaõnnestus rassemiline)

- Pope - Peachey : h20/soolhape
(65-80 % d sõltub ajast)

Eelistan meetodit h20-ga, kuna see on odavam, kiirem ja lihtsam.

Ma loodan, et ma suutsin aidata.
