Transesterification - Wikipedia
WebTransesterification is the process of exchanging the organic functional 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. Strong acids catalyze the reaction by donating a proton to the carbonyl group, thus making it a more potent electrophile.

Transesterification - Process, Reaction Mechanism, Applications
WebTransesterification is an organic reaction in which the R group of an alcohol is exchanged with an R’ group of an ester. This is generally done via the introduction of an acid or base catalyst to the reaction mixture. However, it can also be done using certain enzyme catalysts (such as lipases). An illustration detailing the exchange of an R ...

WebTransesterification represents a mild and versatile alternative to esterification reactions between an acid and an alcohol. This transformation takes place via an alkoxy moiety exchange between an ester and an alcohol (Equation (31)). This is more useful if one of the reaction components is inexpensive as the equilibrium mixtures formed require ...
