METHOD FOR PRODUCING METHIONINE AND/OR 2-HYDROXY-4-(METHYLTHIO) BUTANOIC ACID

摘要

21- METHOD FOR PRODUCING METHIONINE AND/OR 2-HYDROXY-4-(METHYLTHIO) BUTANOIC ACID An object of the invention is to provide a simple method for producing methionine and/or 2-hydroxy-4- (methylthio)butanoic acid at a high yield using 3- 10 (methylthio)propionaldehyde as a raw material. An oxide catalyst containing cerium, 3-(methylthio)propionaldehyde, a compound containing cyanide ion, ammonia or a compound containing ammonium ion, and water are contacted with each other to produce methionine and/or 2-hydroxy-4-(methylthio)butanoic acid. 15 Figure for publication: None
