Ethyl ethanoate is the ester produced when ethanol and ethanoic acid react in the presence of an acid catalyst.
ethanoic acid + ethanol ⇋ ethyl ethanoate + water
CH₃COOH (l) + CH₃CH₂OH (l) ⇋ CH₃COOCH₂CH₃ (l) + H₂O (l)
The ethyl ethanoate produced is an ester.
The reaction is called esterification.
The reaction can also be described as a condensation reaction because water is made when two molecules join together.
