ABSTRACT:
Carboxylic esters are prepared by a process, which comprises reacting dicarboxylic or polycarboxylic acids or their anhydrides with alcohols in a liquid medium with the concomitant removal of water formed by the esterification reaction by azeotropic distillation together with the alcohol in the medium, wherein the amount of liquid removed from the reaction medium by azeotropic distillation is replaced in whole or in part with the alcohol.
