An improved process for preparing diaryl esters of dicarboxylic acids is disclosed, in which the esterification reaction is optimized by removing water and other by-products of the reaction according to a predetermined pattern. The removal of water and other by-products of the esterification reaction is most easily carried out by a distillation means, and the rate of removal is controlled by varying the reflux ratio in the distillation means during the course of the esterification reaction. The diaryl esters so prepared are useful in making linear polyesters.

Process of manufacturing diaryl esters of dicarboxylic acids

An improved process for preparing diaryl esters of dicarboxylic acids is disclosed, in which the esterification reaction is optimized by gradually increasing the temperature at which the reaction is being conducted according to a predetermined pattern. The temperature increase should be a function of the degree of esterification. The diaryl esters so prepared are useful in making linear polyesters.

An improved process for preparing diaryl esters of a monohydroxy aromatic compound with dicarboxylic acids is disclosed, in which the esterification reaction is optimized by continuously removing water and/or other by-products of the reaction from the reactor, while supplying to the reactor a make-up amount of the monohydroxy aromatic compound containing no more than about 100 ppm of water. The make-up stream may be obtained by stripping the by-product stream of water and other by-products of the reaction.
