Método para producir metionina |
摘要 |
A novel method capable of producing methionine without using hydrogen cyanide as a raw material has been desired. The present invention relates to a method for producing methionine including Step A of oxidizing 4-methylthio-2-oxo-1-butanal in the presence of an alcohol, and Step B of reductively aminating 4-methylthio-2-oxo-butyrate obtained in Step A. It is preferable that Step A is carried out by reacting 4-methylthio-2-oxo-1-butanal, the alcohol and an oxidizing agent in the presence of a carbene catalyst. |
