Interesterification involves an exchange of acyl group among triglycerides. Acyl groups may exchange positions within a triglyceride or among triglyceride molecules.


High temperature catalysts: KOH and NaOH

Low temperature catalysts: Sodium Methoxide (NaOCH3)

Reaction Mechanisms

1. The formation of enolate ion

2. The formation of Beta-Keto ester

3. Interesterification

Catalyst Function in Interesterification

Initial removal of an ?-proton by the base catalyst leads to the charge delocalized enolate anion.
