titleOfInvention | Process for the preparation of methionine |
abstract | A new process capable of producing methionine without the use of hydrogen cyanide as the starting material has been desired. The present invention relates to a process for the preparation of methionine comprising the step A of oxidizing 4-methylthio-2-oxo-1-butanal in the presence of an alcohol and step B of the reductive amination of the 4-methylthio-2 obtained in step A. -oxo-butyrate. It is preferred 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. |
