Abstract
Improvements introduced in the subject of the main patent no. 202,871 by process for the preparation of monoesters of terephthalic acid by preferably catalytic oxidation of esters of p-toluºlicos acid with elemental oxygen or gases containing oxygen in liquid phase optionally under pressure characterized by subjecting esters of p-toluyl acids with aromatic alcohols, preferably with p-toluyl alcohol, to oxidation.
