Description:
GBL 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.
 
Application:
1) Used to produce a-pyrrolidone, 1-Methyl-2-pyrrolidinone, polyvinyl pyrrolidone, and α -Acetyl-γ -butyrolactone;
2) used as anaesthetic and tranquilizer, used to produce ciprofloxacin and interferon, as the intermediate of vitamin and rolicyprine;
3) As antioxidant, plasticizer, extractant, adsorbent, dispersant, fixative and curing agent;
4) Used in battery, capacitor and development of color film
