METHOD FOR SYNTHESIS OF GAMMA-AMINOBUTYRIC ACID FROM GLUTAMIC ACID USING HIGH-TEMPERATURE AND HIGH-PRESSURE WATER

摘要

PROBLEM TO BE SOLVED: To provide a method for synthesizingγ-aminobutyric acid from glutamic acid by a high-temperature high-pressure water reaction. SOLUTION: Gamma-aminobutyric acid is synthesized by the high-temperature high-pressure water reaction of glutamic acid (preferably at 280-300°C). The production efficiency of theγ-aminobutyric acid is remarkably improved by adding a substance capable of reacting with the amino group of glutamic acid to form a Schiff's base (e.g. pyruvic acid) before the reaction.
