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. This chemical is incompatible with strong oxidizers. (NTP, 1992). This chemical is incompatible with strong oxidizing agents. It is also incompatible with strong acids, strong bases and strong reducing agents. (NTP, 1992).
