Os tópicos do l-PAC são sempre invadidos instantaneamente por pessoas que fazem besteira, portanto, digo adeus.

Você tem as informações mais importantes: Acetaldeído ou Piruvato, uma levedura adequada e ph <5.

Ninguém fez a grande e óbvia pergunta: Como posso saber se uma cepa de levedura é boa ou não?
E como ninguém perguntou, não haverá resposta a não ser a menção de que existem métodos bastante fáceis.
Boa pesquisa, não me envie uma mensagem.

Tchau

L-PAC and solvent, add methylamine gas into the mixture, no reaction after 10 hours at room temperature. Does the reaction require heating?

The amount of methylamine gas is too small and has not come into contact with the PAC. Ignore this issue.

Having received the product, now preparing to test whether the structure is racemic.

The resulting of L-Ephedrine Hydrochloride has a purity> 98%, matching exactly that of the L-PAC, no racemization occurred.
The entire synthetic process has been successful.:D

The product is racemic after reduction with NaBH4, need to use catalyst/H2.
