Oil Painting Techniques. Fatty acids are carboxylic acids with a long unbranched hydrocarbon (aliphatic) Once the saponification reaction is complete, sodium chloride is added to precipitate the soap. In chemistry terms, saponification involves base (usually NaOH or KOH) hydrolysis of triglycerides, which are esters of fatty acids, to form the sodium salt of a carboxylate. Saponfication crude is a concentrate of the "sweetwater" from fat hydrolysis or "splitting. Cold Process Soap making is a process of adding fats to sodium hydroxide in solution, the resulting reaction, called saponification, produces soap and glycerin. Although ester hydrolysis is catalyzed by both hydrogen and hydroxide ions (19,20), a base-catalyzed esterification is not known. It is a measure of the average molecular weight (or chain length) of all the fatty acids present. After saponification has occurred, the soap is sometimes precipitated from the solution by adding salt, and the excess liquid drained off. Soap is precipitated as a solid from the suspension by adding common salt to the suspension. Saponification Reaction. saponification is the process that converts oil or fat into soap an alcohol with the attendance of an alkali (aqueous) and heat.
