Background

Transesterification, i.e. the reaction of an ester with an alcohol/acid/ester (different ester) under acid or base catalysis to form a new ester and a new alcohol/acid/ester. The esterification reaction is a reversible reaction, in which small amounts of free alcohol and acid are present in the solution of the ester. The transesterification reaction proceeds based on the reversibility of the esterification reaction. The alcohol in the transesterification reaction is capable of undergoing an esterification reaction with a small amount of free acid in the ester solution, and new esters and new alcohols are formed by the new esterification reaction.
