ABSTRACT:
A method and system for increasing conversion efficiency of aromatic alkyl reactant to aromatic carboxylic acid product and for improving the quality of the product, are disclosed. The method and system provide for the continuous production of an aromatic carboxylic acid by the liquid phase, exothermic oxidation of an aromatic alkyl in a vaporizable solvent in an oxidation reactor. The reactor makes use of a vented, overhead condenser system and a separator system for condensation of vaporized reactor material, separation of the condensed solvent therefrom, and reflux of separated solvent back into the reactor. The improvement comprises combining the reactor liquid feedstream with the refluxed solvent upstream from the oxidation reactor.
