2-羟基-4-甲硫基-丁酸 - Production method

Methylthiopropionaldehyde is formed by the reaction of propionaldehyde and methyl mercaptan under the action of a catalyst, and then 2-hydroxy-4-methylthiobutyronitrile is synthesized by catalysis with cyanic acid, and finally in the presence of excess sulfuric acid Hydrolyzed into 2-hydroxy-4-methylthiobutyric acid.
