Example of Methamphetamine Isomers Separation

Takšen mora biti..

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?

Priporočil bi vam zamrzovalnik. V tem primeru velja, da čim hladneje, tem bolje. Temperature niso bile nikoli izmerjene, metanol vedno shranjujem v zamrzovalniku.

-Polarnost (testirana s polarimetrom) po enem prehodu

- H20 (68-73 % d)

- Metanol (71-76 % d)

- Rusznakov postopek, toluen kot nadomestek za benzen (še vedno ni bil racemičen)

- Pope - Peachey: h20/hidroklorna kislina
(65-80 % d je odvisen od časa)

Zaradi stroškov, časa in preprostosti imam raje metodo s h20.

Upam, da sem vam lahko pomagal.
