General Description

Clear colorless liquid.

Air & Water Reactions

Pivalolactone. is unstable in water. Slowly hydrolyzes

Reactivity Profile

Pivalolactone. 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. Pivalolactone. is incompatible with alkanes.

Fire Hazard

Flash point data for Pivalolactone. are not available; however, Pivalolactone. is probably combustible.

Safety Profile

Poison by ingestion. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes.
