the hydrolysis of carboxylic and derivatives, including esters, nitriles, and amides, for example

RCOOR’ + H2O → RCOOH + R’OH

Saponification is widely used in industry to produce acids and alcohols. Higher aliphatic carboxylic acids, glycerol, soaps, and stearic acid are formed upon saponification of fats.
