Question
What is the process used for the manufacture of soaps?
- Ion exchange process
- Saponification
- Distillation
- Steam distillation
Hint:
Hydrolysis of esters to form salts of alcohols and carboxylic acids under acidic or essential conditions.
The correct answer is: Saponification
Saponification is the process used for the manufacture of soaps.
Soaps are made from naturally occurring animal fats and vegetable oils. Animal fats and vegetable oils are esters of alcohols, propane-1,2,3-triol (glycerol) CH2OHCH2OHCH2OH, and long-chain carboxylic acids (often called fatty acids) RCO2H, with alkyl groups from 7 to 21 carbon atoms. This process is known as saponification and the sodium salt of the acid is soap.
