Abstract

PURPOSE: To obtain high purity terephthalic acid and its dimethyl ester in high yield by the catalytic treatment of the reaction mixture containing p-toluic acid and terephthalic acid monomethyl ester as main components, which are obtained by the liquid phase O2 oxidation of p-xylene, in the presence of H2.
