Abstract

Process for the preparation of methionine, which comprises the reaction of the beta-methylmercapto-propionic aldehyde with hydrocyanic acid (or its sodium salt) and ammonia (or an ammonium salt), in an aqueous ammoniacal medium, to produce gamma-methylmercapto-alpha- aminobutyronitrile, characterized in that the volatile impurities present in the reaction mass are eliminated, and the ammonia dissolved therein is recovered by applying a vacuum, with subsequent acid hydrolysis of the entire reaction mass thus treated, using an acid solution sulfuric acid, and neutralization of the acid solution of methionine sulphate with an aqueous ammoniacal solution.
