Vorschrift

A mixture of 0.212 g of p-xylene, 0.011 g of hexahydro-1,3,5-trihydroxy-1,3,5-triazine-2,4,6-trione (3% by mole relative to p-xylene), 0.013 g of N,N′-diacetoxypyromellitdiimide (2% by mole relative to p-xylene), 5 g of acetic acid, 0.003 g of cobalt(II) acetate.4H2O and 0.003 g of manganese(II) acetate.4H2O was stirred at 100° C. in an atmosphere of oxygene gas (1 atm=0.1 MPa) for 14 hours. The resulting product in the reaction mixture was analyzed by high performance liquid chromatography and was found to yield terephthalic acid in 97% yield at 100% conversion of p-xylene.
