Abstract
A process for the preparation of dialkyl esters of terephthalic acid, characterized in that a mixture of a liquid lower alkanol and terephthalic acid, in a molar ratio of at least 25 to 1, at a temperature of at least about 150º c, is heated at a pressure of at least about 20 atmospheres and in the absence of catalyst, until substantially all of the terephthalic acid has been converted to the diester and recovered said diester from the reaction mixture.
