| gamma-Butyrolactone Usage And Synthesis |
Chemical Properties | colourless oily liquid | Usage | r-butyrolactone is one kind of important fine chemicalintermediate, simultaneously also is one kind of performance fine highboiling point solvent, ideal antioxidant, plasticizer,extracting agent, absorbent, dispersing agent, solid stain, Coagulation Reagent. | General Description | Clear colorless oily liquid with a pleasant odor. | Air & Water Reactions | Hygroscopic. Soluble in water. | Reactivity Profile | gamma-Butyrolactone can react with oxidizing materials, inorganic acids and bases, alcohols and amines. Rapidly hydrolyzed by bases and slowly hydrolyzed by acids. gamma-Butyrolactone is volatile with steam. . The combination of the lactone, butanol, 2,4-dichlorophenol, and sodium hydroxide in the attempted synthesis of 2,4-dichlorophenoxybutyric acid caused a thermal runaway reaction that eventually exploded, [CISHC Chem. Safety Summ., 1977, 48, 3]. | Fire Hazard | gamma-Butyrolactone is combustible. |
