An ester is a compound formed from an acid and an alcohol. In esters of carboxylic acids, the -COOH group and the -OH group lose a water and become a -COO- linkage: R-COOH + R'-OH = R-COO-R' + H2O where R and R' represent organic groups.

"Phenols react with carboxylic acids so slowly that the reaction is unusable for preparation purposes. Esters are produced when carboxylic acids are heated with alcohols in the presence of an acid catalyst. The catalyst is usually concentrated sulphuric acid."
