摘要
Disclosed is a process for manufacturing an aromatic diacid in one step with a single catalyst system which comprises: a) introducing into a reactor an aromatic hydrocarbon containing the number of rings desired in the product diacid with one or more alkyl groups attached to the rings; b) reacting said aromatic hydrocarbon in the presence of an oxidant supply and a single catalyst system comprising at least one catalyst selected from Group IB, IIB, VB, or VIIB of the Periodic Table, in a reaction medium capable of stabilizing the aromatic acids formed against further oxidation to water and CO2, or decarboxylation to aromatic hydrocarbons, and also capable of allowing the isomerization of the acids so formed to the desired diacids; and c) reacting said hydrocarbon feed with said oxidant in the presence of said catalyst system until a desired amount of said feed is oxidized to carboxylic acids and isomerized to the desired diacid product.
