gamma-Valerolactone Usage And Synthesis

Chemical Properties CLEAR COLOURLESS LIQUID
General Description Clear, colorless, mobile liquid. pH (anhydrous): 7.0. pH (10% solution in distilled water): 4.2.
Air & Water Reactions Water soluble.
Reactivity Profile gamma-Valerolactone is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. gamma-Valerolactone is incompatible with strong oxidizers. . gamma-Valerolactone is incompatible with strong oxidizing agents. gamma-Valerolactone is also incompatible with strong acids, strong bases and strong reducing agents. .
Fire Hazard gamma-Valerolactone is combustible.
