ABSTRACT:
This invention relates to a new catalyst and to a novel oxidation process. In this novel process, aromatic compounds with an alkyl group having at least one alpha hydrogen, including aromatic compounds wherein the alkyl groups are unsubstituted and substituted, are contacted in the liquid phase at reaction conditions with an oxygen-containing gas in the presence of a novel catalyst which is prepared by milling an anhydrous transition metal halide with silver nitrite, the transition metal being selected from the Groups IVb to VIII and Ib and IIb of the Periodic Table, wherein the mole ratios of metal halide to silver nitrite are in the ratio of 1:1 to 1:5.
