Abstract
The efficiency of catalyzed batch esterification reactions is improved by the use of a particular temperature and pressure profile during the reaction cycle. In particular elevated pressure is maintained to prevent alcohol boil off during initial mixing and reaction of the reactants prior to any catalyst addition, and preferably the pressure is reduced rapidly after the desired reaction temperature has been reached.
