Abstract
Process for obtaining high purity terephthalic acid in which a p-substituted aromatic compound is catalytically oxidized with molecular oxygen gas in the presence of aliphatic carboxylic acid as a solvent and in coexistence with an oxidation catalyst and bromine or bromine compound, characterized because upon completion of the oxidation reaction, the respective mixture is again catalytically oxidized with gaseous molecular oxygen at a temperature of 200 to 300ºC which is higher than the above oxidation temperature.
