Gamma Butyrolactone is an important chemical raw material and intermediate for medicine, and also the intermediate of the synthesize N-methyl pyrrolidone, α -pyrrolidone, polyvinyl pyrrolidone, α -acetyl-γ -butyrolactone, methionine and the butyric acid compounds. This product features a strong solubility, and is a good solvent for polyacrylonitrile, epoxy resin, polyvinyl butyral, polyvinyl chloride and its copolymers, and cellulose polymers. In medical industry, it is mainly used in synthesizing cyclopropylamine, etc
gamma-Butyrolactone(GBL) introduction:
Gamma-Butyrolactone (γ-butyrolactone or GBL) is a hygroscopic colorless liquid with a weak characteristic odor which is soluble in water. GBL is a common solvent and reagent in chemistry as well as being used as a flavouring, as a cleaning solvent, as a superglue remover, and as a solvent in some wet aluminium electrolytic capacitors. In humans it acts as a prodrug for GHB, and it is used as a recreational intoxicant with effects similar to alcohol.
GBL is a lactone. It is hydrolyzed under basic conditions, for example in a sodium hydroxide solution into sodium gamma-hydroxybutyrate, the sodium salt of gamma-hydroxybutyric acid. Under acidic conditions it forms an equilibrium mixture of both compounds. These compounds then may go on to form a polymer. When treated with a non-nucleophilic base, like lithium diisopropylamide, GBL can become an alpha-carbon nucleophile. The related compound caprolactone can be used to make a polyester in this manner.
GBL is rapidly converted into GHB by paraoxonase (lactonase) enzymes, found in the blood.[7][8] Animals which lack these enzymes exhibit no effect from GBL.[7] GBL is more lipophilic (fat soluble) than GHB, and so is absorbed faster and has higher bioavailability. Because of these pharmacokinetic differences, GBL tends to be more potent and faster-acting than GHB, but has a shorter duration; whereas the related compound 1,4-butanediol (1,4-B) tends to be slightly less potent, slower to take effect but longer-acting than GHB.
