ABSTRACT:
A process for the manufacture of polycarboxylic acids is disclosed. In this novel process, antimony is used to improve the selectivity of cobalt-manganese-bromine or zirconium-cobalt-manganese-bromine oxidation system. Polymethylbenzenes such as pseudocumene are converted to their corresponding polycarboxylic acids which are used to manufacture plasticizers and polyamide-imide polymers used as molding compounds for replacement of metals.
