Method for producing methionine |
abstract |
There has been a demand for a new method capable of producing methionine without using hydrogen cyanide as a raw material. Step A in which 4-methylthio-2-oxo-1-butanal is oxidized in the presence of alcohol, Step B in which 4-methylthio-2-oxo-butanoic acid ester obtained in Step A is hydrolyzed, and A method for producing methionine, comprising a step C of reductive amination of 4-methylthio-2-oxo-butanoic acid obtained in step B. [Selection figure] None |
