Abstract
Procedure for the preparation of terephthalic acid, isophthalic acid or its monomethyl esters by oxidation of para-xylene, meta-xylene or the corresponding liquid phase methyl esters of toluilic acid with the joint use of a catalyst containing cobalt and bromine at elevated temperature and high pressure; characterized in that the oxidation is carried out in a solution in acetic acid of alkali metal acetate.
