Abstract
Method of preparing methionine, characterized in that it comprises the reaction of hydrogen cyanide and methyl mercaptan with acrolein to form alpha-hiaroxy-gacima-methylthiol-butyroaitrile, reacting such nitrile with ammonia to convert the hydroxylic group to an amine group, and hydrolyze the group of nitrile to form a carboxyl group.
