Neutral Fat Saponification. In the saponification of triglycerides with an alkali, the two reactants are rather immiscible. Because saponification is a bimolecular nucleophilic substitution (Sn ), the kinetic rate enhancement of this reaction is achievable by both a high-shear mixing and an increase in the reaction temperature during the processing. The saponifiction reaction is self-catalyzed to some extent the formation of soap product effects the emulsification of the two immiscible reactants, causing an acceleration of the reaction rate.
