Ethyl benzoate, C9H10O2, is an ester formed by the condensation of benzoic acid and ethanol. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents.

As with many volatile esters, ethyl benzoate has a pleasant odor described as sweet, wintergreen, fruity, medicinal, cherry and grape.[1] It is a component of some fragrances and artificial fruit flavors.

Preparation

A simple and commonly used method for the preparation of ethyl benzoate in the laboratory is the acidic esterification of benzoic acid with ethanol and sulfuric acid as catalyst:[2]

Reaction equation for the acidic esterification.
