Saponification vs. Transesterification



(chemistry) The hydrolysis of an ester under basic conditions to form an alcohol and the salt of the acid.


(organic chemistry) The reaction of an ester with an alcohol in order to replace the alkoxy group; it is used in the synthesis of polyesters and in the production of biodiesel


The reaction of a metallic alkali (base) with a fat or oil to form soap.


In organic chemistry, transesterification is the process of exchanging the organic group R″ of an ester with the organic group R′ of an alcohol. These reactions are often catalyzed by the addition of an acid or base catalyst.


The act, process, or result, of soap making; conversion into soap; specifically (Chem.), the decomposition of fats and other ethereal salts by alkalies; as, the saponification of ethyl acetate.


a chemical reaction in which an ester is heated with an alkali (especially the alkaline hydrolysis of a fat or oil to make soap)



Saponification is a process that involves the conversion of fat, oil, or lipid, into soap and alcohol by the action of aqueous alkali (e.g. NaOH).) Soaps are salts of fatty acids, which in turn are carboxylic acids with long carbon chains.
