production

Methyl acetate is produced industrially by carbonylation of methanol as a byproduct of acetic acid production. It is also formed by the esterification of methanol with acetic acid in the presence of strong acids such as sulfuric acid. This production process, which Eastman Kodak accelerated using reactive distillation, is quite famous.

General features

Methyl acetate, also known as methyl ethanoate, is a carboxylated ester. Some glues or nail polish removers have an odor reminiscent of the characteristic pleasant smell. Although it is sometimes used as a lipophilic solvent, ethyl acetate is preferred as it is less toxic and less soluble in water. Methyl acetate is not stable in the presence of dilute acids or bases.

Usage areas

Methyl acetate is used in industry as a volatile solvent and in the production of cellulosic glues in fast-drying paints. In lacquer production, it acts as a viscosity reducer. Also, some perfumes and nail polish removers contain methyl acetate.

Safety Precautions and Toxicity

Although methyl acetate does not cause serious health problems at low concentrations, it is harmful at high concentrations. May cause skin dryness and cracks in contact with skin. When inhaled, it causes problems such as nausea and dizziness. Methyl acetate is flammable and care must be taken when mixing with oxidizing agents. May form explosive mixtures in air at high temperatures. It should be stored in tightly closed containers.
