Properties

Ethyl acetate is a colorless liquid with a pleasant smell. It dissolves well in alcohol, chloroform and other organic solvents but dissolves less well in water. It is an excellent solvent itself.

If inhaled in high concentrations it causes stupor. As it is exposed to light it breaks down into alcohol and acetic acid in air. It is a short-chain ester.

Occurrence and production

Ethyl acetate is prepared in industry using the Tishchenko reaction, from acetaldehyde, or in a reaction of ethanol and acetic acid, using concentrated sulphuric acid as a catalyst and a dehydrating agent.

Uses

Ethyl acetate is used as a solvent in industrial quantities and in the production of varnishes, films, explosives, artificial leather, cellophane and ethyl acetoacetate.
