Methyl Acetate

Description: Methyl acetate, acetic acid methyl ester or methyl ethanoate, is a carboxylate  ester. Methyl acetate is produced industrially via the  carbonylation of  methanol as a byproduct of the production of  acetic acid. Methyl acetate also arises by  esterification of acetic acid with methanol in the presence of strong acids such as  sulfuric acid.

Application: A major use of methyl acetate is as a volatile low toxicity  solvent in glues, paints, and nail polish removers.
