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?

Бих препоръчала превода на фризера. В този случай колкото по-студено, толкова по-добре. Температурите никога не са били измервани, аз винаги съхранявам метанола си във фризера.

-Полярността (тествана с поляриметър) след едно преминаване

- H20 (68-73% d)

- Метанол (71-76% d)

- Процес на Руснак, толуол като заместител на бензола (все още не успява рацемичен)

- Pope - Peachey: h20/солна киселина
(65-80 % d е в зависимост от времето)

Предпочитам метода с h20 заради цената, времето и простотата.

Надявам се, че ще мога да помогна.
