saponification

[sə‚pän·ə·fə′kā·shən]
(chemistry)
The process of converting chemicals into soap; involves the alkaline hydrolysis of a fat or oil, or the neutralization of a fatty acid.

Saponification

 

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.

saponification

The conversion into soap which occurs when an alkali, such as the lime in cement, reacts with oils in paint; destroys the adhesion and strength of oil-based paint films.
