      Uses:
      
(1) GBL can be used to produce a-pyrrolidone, 1-Methyl-2-pyrrolidinone , polyvinyl pyrrolidone, and α-Acetyl-γ-butyrolactone, etc.
      
(2)GBL can be used as anaesthetic and tranquilizer, used to produce ciprofloxacin and interferon, as the intermediate of vitamin and rolicyprine;
      
(3) GBL is the intermediate of plant growth stimulator and insecticide.
      
(4)GBL is a good antioxidant, plasticizer, extractant and adsorbent, dispersant, fixative and curing agent; moreover, it can also be used in battery, capacitor and development of color film.
