Fischer esterification involves the formation of an ester from a carboxylic acid and an alcohol. The mechanism is an acid promoted acyl substitution, which results in the substitution of an alkoxy group for the hydroxyl portion of the carboxyl group.

Reaction #4 is called esterification, since it is commonly used to convert carboxylic acids to their ester derivatives. ... This type of esterification is often referred to as Fischer esterification. As expected, the reverse reaction, acid-catalyzed ester hydrolysis, can be carried out by adding excess water.

An interesting question involving esterification reactions like 11 and 12 involves the identities of the oxygen atoms in the reactants and products. In other words, does the OH group of the water come from the alcohol or from the carboxylic acid?

If this energy difference is considered, then the overall reaction energy for the esterification reaction becomes exothermic by about 3.6 kcal/mol.
