Synthesis Of Banana Oil Mechanism
Esterification is used to derivatize carboxylic acids and other acidic functional groups. In a typical reaction, Esterification involves the condensation of the carboxyl group of an acid and the hydroxyl group of an alcohol, with the elimination of water (Konwar, 2008). Many Esterification reactions are slow and elevated temperatures are frequently used. Since the Esterification reaction is an equilibrium reaction, it may be necessary to remove the water generated during the reaction. The chemical industry uses esters for a variety…...
