Riga 38:
: RCO<sub>2</sub>R′ + CH<sub>3</sub>OH → RCO<sub>2</sub>CH<sub>3</sub> + R′OH
Like the hydrolysation, transesterification is catalysed by acids and bases. The reaction is widely used for degrading [[triglyceride]]s, e.g. in the production of fatty acid esters and alcohols. [[Poly(ethylene terephthalate)]] is produced by the transesterification of [[dimethyl terephthalate]] and ethylene glycol:<ref name=Ullmann
: (C<sub>6</sub>H<sub>4</sub>)(CO<sub>2</sub>CH<sub>3</sub>)<sub>2</sub> + 2 C<sub>2</sub>H<sub>4</sub>(OH)<sub>2</sub> → {{frac|''n''}} {(C<sub>6</sub>H<sub>4</sub>)(CO<sub>2</sub>)<sub>2</sub>(C<sub>2</sub>H<sub>4</sub>)}<sub>''n''</sub> + 2 CH<sub>3</sub>OH
Riga 60:
Alcoholysis of acyl chlorides and acid anhydrides
Alcohols react with [[acyl chloride]]s and [[acid anhydride]]s to give esters:
: RCOCl + R′OH → RCO<sub>2</sub>R′ + HCl
: (RCO)<sub>2</sub>O + R′OH → RCO<sub>2</sub>R′ + RCO<sub>2</sub>H
