- CH2-OH -CH-OH - CH2-OH (glycerol) + 3 R-CO2-Na (soap) R=(CH2)14CH3 (for example)
Sodium chloride is added to precipitate the soap.
Vegetable oils and animal fats are fatty esters in the form of triacylglycerols . The alkali breaks the ester bond and releases the fatty acid and glycerol.
The soap is salted out by precipitating it with sodium chloride.
Saponification can also refer to the conversion of fat and other soft tissue in a corpse into adipocere. This process is more common where the amount of fatty tissue is high, the agents of decomposition absent or only minutely present, and the burial ground is particularly alkali.
Fires involving cooking fats and oils should be extinguished with a wet chemical extinguisher. Extinguishers of this type are designed to extinguish cooking fats and oils through saponification.
The extinguishing agent rapidly converts the burning substance to a non-combustible soap. This process also has a cooling effect, and suppresses the flames with steam.
