Ilyennek kell lennie.

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?

Ajánlom a fagyasztót. Ebben az esetben minél hidegebb, annál jobb. A hőmérsékleteket soha nem mértük, a metanolomat mindig a fagyasztóban tárolom.

-A polaritás (polariméterrel tesztelve) egy átjárás után.

- H20 (68-73% d)

- Metanol (71-76% d)

- Rusznak-eljárás, toluol mint benzolhelyettesítő (még mindig nem sikerült racém)

- Pope - Peachey : h20/sósav
(65-80 % d időfüggő)

Én a h20-as módszert részesítem előnyben a költségek, az idő és az egyszerűség miatt.

Remélem tudtam segíteni.
