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?

Dondurucuyu tavsiye ederim. Bu durumda, ne kadar soğuk o kadar iyi. Sıcaklıklar hiç ölçülmedi, metanolümü her zaman dondurucuda saklarım.

-Bir geçişten sonra polarite (polarimetre test edildi)

- H20 (%68-73 d)

- Metanol (%71-76 d)

- Rusznak süreci, benzen ikamesi olarak toluen (hala başarısız rasemik)

- Pope - Peachey : h20/hidroklorik asit
(%65-80 d zamana bağlıdır)

Maliyet, zaman ve basitlik nedeniyle h20 ile yöntemi tercih ediyorum.

Umarım yardımcı olabilmişimdir.
