CH3COOEt

CH3COOEt, commonly known as ethyl acetate, is the ethyl ester of acetic acid and ethanol. Its chemical formula is C4H8O2 and its IUPAC name is ethyl ethanoate. It is a colorless, volatile liquid with a characteristic fruity odor and is widely used as a solvent in industry and laboratories.

Production and processing: Ethyl acetate is primarily produced by the esterification of acetic acid with ethanol in the presence of an acid catalyst, such as sulfuric acid or an ion-exchange resin. Water removal drives the reaction toward ester formation. It can also be obtained via transesterification processes or as a byproduct in some acylation reactions. After synthesis, it is typically dried and purified by distillation.

Properties: Ethyl acetate has a boiling point around 77°C and a low flash point, making it highly flammable. It is miscible with many organic solvents and is partially soluble in water (roughly a few grams per 100 milliliters at room temperature). It evaporates readily and forms vapors that can be irritating in high concentrations. The compound is readily biodegradable and has a relatively moderate environmental profile when handled and disposed of properly.

Uses: It is one of the most common organic solvents, employed in coatings, inks, adhesives, and cleaners. In the fragrance and flavor industries, ethyl acetate serves as a solvent and a constituent of aroma formulations. It also appears in nail polish removers and various laboratory extraction procedures.

Safety and handling: Due to its flammability, ethyl acetate should be stored in a well-ventilated area away from ignition sources, with containers kept tightly closed. Protective equipment such as gloves and goggles is recommended, and exposure should be minimized to prevent irritation and dizziness. Proper disposal follows local regulations for volatile organic compounds.
