Description
Ethyl benzoate, C9H10O2, is the 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 which could be described similar to wintergreen mint. It is a component of some artificial fruit flavors.
Chemical Properties
colourless liquid with an aromatic odour
Chemical Properties
Ethyl benzoate has a somewhat fruity odor similar to ylang-ylang, but milder than methyl benzoate

It has a role as a flavouring agent, a fragrance and a volatile oil component. It is a benzoate ester and an ethyl ester.
Preparation
By esterification of ethyl alcohol and benzoic acid in the presence of anhydrous aluminum sulfate and a trace of sulfuric
acid; by transesterification of methyl benzoate with ethanol in the presence of potassium ethylate
