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?

Ik zou de vriezer aanraden. In dit geval geldt: hoe kouder, hoe beter. De temperaturen zijn nooit gemeten, ik bewaar mijn methanol altijd in de vriezer.

-De polariteit (polarimeter getest) na één passage

- H20 (68-73% d)

- Methanol (71-76% d)

- Rusznakproces, tolueen als benzeenvervanger (nog steeds geen racemisch resultaat)

- Pope - Peachey: h20/chloorwaterstofzuur
(65-80% d is afhankelijk van de tijd)

Ik geef de voorkeur aan de methode met h20 vanwege de kosten, tijd en eenvoud.

Ik hoop dat ik kon helpen.
