The oxidation of p-xylene to produce terephthalic acid is carried out using pure or nearly pure oxygen and evaporative cooling. By-product and waste generation are reduced, oxygen utilization is enhanced, desirable operating conditions are employed, and the need for direct contact heat exchange surfaces in the reactor vessel is obviated.
