ABSTRACT:
An integrated process for oxidizing aromatic and alkyl aromatic compounds to form carbonyl containing reaction products comprising the reaction of quadravalent cerium with a reactant stream containing an aromatic or alkyl aromatic compound and using a high degree of mixing, followed by the electrolytic regeneration of the reduced cerium ion in a cell under near turbulent or turbulent flow conditions at high solution velocities relative to the anode. The preferred cell structure for accomplishing the electrolysis utilizes an turbulence promoting anode arrangement which allows for the anolyte to flow past the anode under the conditions mentioned, and a reduced area cathode whereby the anode and cathode compartments need not be separated by an ion exchange membrane.
