Description and Uses
Methyl trimethylacetate is a colorless liquid, the methyl ester of pivalic acid. The ester is well known for being resistant to hydrolysis to the parent acid. Hydrolysis can be effected with a solution of trimethylsilyl iodide in hot acetonitrile followed by aqueous workup. It is used to make vinyl chloride resins, as a chemical intermediate, and in adhesives, lubricants, greases, and fuel additives.
Methyl Pivalate is a useful chemical reagent for the preparation of esters and transesterification.
