Chemical synthesis method and application of gamma aminobutyric acid

The invention discloses a chemical synthesis method and application of gamma aminobutyric acid in the technical field of synthesis and application of gamma aminobutyric acid. The chlorination reaction and the esterification reaction are carried out at the same time when the gamma aminobutyric acid is synthesized, the reaction time is shortened, high-pressure equipment is not used, a catalyst is not used, the influence of the catalyst on aftertreatment is avoided, the second-step product is good in quality and high in yield, and the process route is mild in reaction condition, easy to operate, low in cost and suitable for large-scale industrial production; gamma-aminobutyric acid is added into the yellow feather broiler feed, so that the feed intake and weight loss caused by heat stress treatment are reversed, and the gamma-aminobutyric acid improves the weight of the yellow feather broiler by improving appetite loss caused by high temperature. 本发明公开了γ氨基丁酸合成及应用技术领域的一种γ氨基丁酸的化学合成方法及应用。本发明在合成γ氨基丁酸时将氯化反应和酯化反应同时进行，
