Abstract
Process for obtaining esters of terephthalic acid, characterized in that neutral salts of terephthalic acid, by a stronger acid than terephthalic acid, and/or corresponding anhydrides and/or acid salts of other benzenecarboxylic acids, are The acid salt of terephthalic acid is converted into acid salt with alcohols or epoxides, optionally in the presence of esterification catalysts, the reaction mixture is decomposed in the terephthalic acid ester and the neutral salt of terephthalic acid becomes to optionally add the neutral salt to the starting material and the terephthalic ester is prepared according to standard methods.
