ABSTRACT:
A method is disclosed for the continuous production of an aromatic carboxylic acid by the liquid phase, exothermic oxidation of an alkyl aromatic in a solvent in an oxidation reactor employing an overhead condenser system for condensation and recycle of vaporized solvent to the reactor, wherein the oxidation is performed at a relatively reduced temperature or pressure or at a relatively increased throughput of the alkyl aromatic without exceeding the elevation head between the condenser system and the reactor.
