Versuchsvorschrift

A mixture of 0.300 g of p-tolyl acetate, 0.018 g of hexahydro-1,3,5-trihydroxy-1,3,5-triazine-2,4,6-trione (5% by mole relative to p-tolyl acetate), 5 g of acetic acid, 0.003 g of cobalt(II) acetate.4H2O, 0.001 g of manganese(II) acetate.4H2O and 0.003 g of 2,2′-azobisisobutyronitrile was stirred at 100° C. in an atmosphere of oxygene gas (1 atm=0.1 MPa) for 6 hours. The resulting product in the reaction mixture was analyzed by gas chromatography and was found to yield 4-acetoxybenzoic acid in 82% yield at 85% conversion of p-tolyl acetate.
