ABSTRACT:
An improvement in the liquid phase air oxidation process based upon a solvent system such as acetic acid and with a bromine activated heavy-metal catalyst system for preparing phthalic, isophthalic and terephthalic acids from their corresponding alkyl benzenes wherein the heavy metal is a soluble cobalt compound and sufficient excess of air is introduced so that the waste gas still contains an excess of oxygen.
