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?

Suosittelen pakastinta. Tässä tapauksessa mitä kylmempi, sitä parempi. Lämpötiloja ei koskaan mitattu, säilytän metanoliani aina pakastimessa.

-Polariteetti (polarimetrillä testattu) yhden läpikäynnin jälkeen.

- H20 (68-73 % d)

- Metanoli (71-76 % d)

- Rusznak-prosessi, bentseenin korvikkeena tolueeni (ei vieläkään onnistunut raseeminen).

- Pope - Peachey : h20/kloorivetyhappo.
(65-80 % d on riippuvainen ajasta).

Suosin menetelmää, jossa käytetään h20:ta, koska se on kustannuksiltaan, ajallisesti ja yksinkertaisuudeltaan parempi.

Toivottavasti pystyin auttamaan.
