Abstract
The present invention provides a process for the production of an ester, including reacting an alcohol with a carbonyl-like compound in the presence of a first esterification catalyst; and adding a second esterification catalyst to the reaction mixture at some time after initiation of the esterification reaction. The staged addition of the esterification catalyst according to the present invention provides a reduced reaction time to achieve a targeted conversion to esters.
