An ester is an organic compound formed from a condensation reaction between an alcohol and a carboxylic acid.

The reaction is generally slow at room temperature and the yield of ester is low. The rate can be by heating the reaction mixture and by using concentrated sulphuric acid as a catalyst. The presence of the concentrated sulphuric acid also increases the yield of ester.

The aim of this experiment is to prepare an ester and to identify some of the characteristic properties of esters.
