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?

Es ieteiktu šo saldētavu. Šajā gadījumā, jo aukstāks, jo labāk. Temperatūra nekad netika mērīta, es vienmēr glabāju metanolu saldētavā.

-Polaritāte (pārbaudīta polarimetrā) pēc viena gājiena

- H20 (68-73% d)

- Metanols (71-76 % d)

- Rušņaka process, toluols kā benzola aizstājējs (joprojām nav racēmisks)

- Pope - Peachey: h20/hidrohlorskābe
(65-80 % d ir atkarīgs no laika)

Es dodu priekšroku metodei ar h20 izmaksu, laika un vienkāršības dēļ.

Es ceru, ka varēju palīdzēt.
