Abstract
Improvements introduced in the object of the main patent No. 202,871 by procedure for the preparation of terephthalic acid monoesters in which for the preparation of benzoldicarboxylic acid monoesters particularly of monomethyl esters by oxidation of toluelic acid esters with elemental oxygen or oxygen-containing gases at increased temperature in liquid phase possibly under pressure conveniently in the presence of catalysts as heavy metal salts are characterized in that o-toluelic acid esters particularly the metal ester are subjected to oxidation.
