Fixed oils Saponification test - Test for Triterpenoids &Steroids Liebermann Burchard test - - + Test . This observation was probably due to the fact that as the reaction proceeded, the reaction started behaving like a first order reaction. Our main study topic is the saponification mechanisms, in a crucial side reaction of alkali-catalyzed transesterification. Saponification involves the reaction of triglycerides natural fats and oilswith sodium or potassium hydroxide. Answer (1 of 10): Saponification is a process by which triglycerides (fats/oils) react with sodium or potassium hydroxide (lye) to produce glycerol and a fatty acid salt known as "soap."
