CH3COOCH3

CH3COOCH3, commonly known as methyl acetate, is an ester with the chemical formula C3H6O2. Its IUPAC name is methyl ethanoate. It is formed by the esterification of acetic acid (ethanoic acid) with methanol, typically in the presence of an acid catalyst, yielding methyl acetate and water.

Methyl acetate is a colorless, volatile liquid with a characteristic fruity odor. It has a boiling point of about 56 °C and a density near 0.93 g/mL at 20 °C. It is flammable and emits vapors that can form explosive mixtures with air. It is miscible with many organic solvents and has limited water solubility, making it a versatile solvent in various chemical processes.

Industrially, methyl acetate is produced primarily by the esterification of methanol with acetic acid. It is also used as an intermediate in organic synthesis and is widely employed as a solvent due to its ability to dissolve a broad range of polar and nonpolar compounds.

Applications typically include use as a solvent in coatings, paints, adhesives, inks, and nail polish removers. It is valued for its fast evaporation rate and relatively low odor compared with some other solvents. In the laboratory, methyl acetate serves as a general-purpose solvent and as a medium for reactions requiring a relatively nonreactive ester solvent.

Safety and handling considerations include its flammability and potential irritation to skin, eyes, and the respiratory system. It should be stored in well-ventilated areas away from heat sources and ignition sources, with proper containment and disposal practices in accordance with local regulations.
