Abstract
The improved process for the production of methyl esters of terephthalic acid by esterification of terephthalic acid with methanol, which comprises reacting terephthalic acid with an excess of methanol in the liquid phase at an elevated pressure and at a temperature above 180º c, in the absence of a catalyst and under conditions such that the water content of the reaction system does not exceed 20% by weight relative to the reaction mixture.
