Abstract
The addition of molybdenum to oxidation catalysts provided by a heavy transition metal-bromine ion combination containing cobalt uniquely increases catalytic activity of said combustion for converting methyl groups to the corresponding carboxylic acid groups on the benzene nucleus. Such greater catalytic activity is manifested by higher yields of aromatic acids. The polycarboxylic acids produced by the novel process are useful as raw materials for fibers and films.
