Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials, and often have a characteristic pleasant, fruity odor.n chemistry, esters are chemical compounds derived from an acid (organic or inorganic) in which at least one-OH (hydroxyl) group is replaced by an-O- alkyl (alkoxy) group. Usually, esters are derived from a carboxylic acid and an alcohol.
