γ-aminobutyric acid is a natural amino acid in plants,microorganisms and vertebrates, is also the central nervous system of Chinese medicine inhibitory neurotransmitter,involved in a variety of metabolic activities,has good thermal stability and water solubility,as well as high physiological activity.The γ-aminobutyric acid seen on the market is generally white to off-white solid powder,soluble in water,we can prepare γ-aminobutyric acid by pyrrolidone.
Preparation of γ-aminobutyric acid,need to digest quicklime with distilled water,get lime milk,put into hydrolysis reaction reactor after adding pyrrolidone,and heated to 125℃~130℃,keep the pressure at 0.29MPa,keep the temperature for more than 10~14 hours,after the completion of the reaction cooling to 30℃,in the discharge filtration,washed with distilled water,Get filtrate and ammonium bicarbonate until to detect the calcium ions can stop adding sodium bicarbonate,add active carbon,and heated to 80 ℃ heat preservation,decoloring and a half hours,filtered when cooled to 60 ℃,using distilled water, lotion and filtrate,at 60 ℃ in decompression,enrichment and precipitation crystallization,adding ethanol in the crystallization,Then cooling,filtering,drying,you can get gamma-aminobutyric acid.
γ-aminobutyric acid is mainly used in medicine,biochemical research,organic chemical industry and other fields,can play a role in the prevention and treatment of various types of liver coma,can also be used to treat gas poisoning,poliomyelitis,cerebral hemorrhage,uremia,cerebral sclerosis and other diseases.In addition, γ-aminobutyric acid also has certain effects on relieving anxiety, improving sleep, improving memory, and promoting metabolism.
