Abstract
Improvements made to the object of main patent no. 202,171 by procedure for the preparation of terephthalic acid monoesters in 1as that for the preparation of benzoldicarboxylic acid monoesters particularly of the monomethyl ester by oxidation of toluene esters with elemental oxygen or oxygen-containing gases at increased temperature in liquid phase optionally under pressure conveniently in the presence of catalysts such as Heavy metal salts are characterized in that m-toluilic acid ester, particularly methyl ester, is subjected to oxidation.
