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.

Abstract: A process for preparing optically active methionine, methionine nitrile, and methionine amide is disclosed. A mixture of L- and D-methionine nitrile is at least partially converted to a salt of optically active Alpha -phenoxypropionic acid, and the resulting salt is subjected to optical separation by crystallization. The resultant optically active methionine nitrile may be converted into methionine or methionine amide. Optically active methionine or methionine amide is useful as a food and feed supplement.

Abstract: THERE IS PROVIDED AN IMPROVEMENT IN THE KNOWN PROCESS OF OPTICAL RESOLUTION OF MIXTURES OF L- AND D-LYSINE BY REACTING THE LYSINE AND FORMING A SALT WITH ONE OF THE OPTICAL ANTIPODES OF A-PHENOXY PROPIONIC ACID. THE IMPROVEMENT COMPRISES USING OPTICALLY IMPURE A-PHENOXY PROPIONIC ACID HAVING OPTICAL PURITIES OF AS LOW AS 70%, INSTEAD OF THE MORE EXPENSIVE OPTICALLY PURE A-PHENOXY PROPIONIC ACID. THE RECOVERY LYSINE HAS AN OPTICAL PURITY GREATER THAN THE PURITY OF THE A-PHENOXY PROPIONIC ACID USED AND THE RECOVERED A-PHENOXY PROPIONIC ACID CAN HAVE A PURITY OF ESSENTIALLY 100%.
