ABSTRACT:
Oxygen or an oxygen-rich gas is used in the production of terephthalic acid in a reaction system that mitigates the flammability hazards associated therewith. Lower reactant and solvent consumption is achieved, with lower production of unwanted by-products, lower gas handling costs and lower environmental impact concerns than with conventional air based terephthalic acid production.
