    Abstract: A process is disclosed for the preparation of lysine and lysine compounds wherein a mixture of 5-(3-cyanopropyl)-hydantoin and 1ureido-4-cyanovaleramide is obtained and hydrogenated in the presence of a catalyst to a mixture of 5-(4-aminobutyl)-hydantoin and 1-ureido-5-aminocapronamide, which in turn is hydrolyzed to lysine or a lysine compound.
