Saponification (Fat + NaOH)

fat + 3NaOH → glycerol + 3 sodium carboxylate (soap)

अवलोकन

Saponification is the base-catalyzed hydrolysis of triglyceride fats or oils by sodium hydroxide to produce glycerol and sodium salts of fatty acids (soap). Unlike acid-catalyzed ester hydrolysis, saponification is irreversible because the carboxylate salt is deprotonated. The reaction requires heating and stirring.

रोजमर्रा का उदाहरण

Handmade soap is produced by heating vegetable oils or animal fats with lye (NaOH) in this ancient saponification reaction.

औद्योगिक महत्व

The global soap industry produces over 25 million tonnes annually. Glycerol byproduct is used in pharmaceuticals, cosmetics, and food processing.
