الإجراء التجريبي

In a 500-ml titanium autoclave equipped with a stirrer and a pressure gauge, 15.36 g of p-toluicacid, 104.0 g of acetic acid, 0.114 g of 1,3,5-triacetoxy-hexahydro-1,3,5-triazine-2,4,6-trione (1,3,5-triacetoxyisocyanuric acid) (0.33% by mole relative to p-toluic acid), 0.112 g of cobalt (II) acetate 4 H2O and 0.277 g of manganese(II) acetate 4 H2O were placed. The autoclave was charged with 2 MPa of oxygen gas and 2 MPa of nitrogen gas and placed in a heated oil bath. The mixture was stirred at 150° C. for 1 hour. After the completion of the reaction, the autoclave was placed on cold water to cool down the reaction mixture quickly. The resulting mixture was analyzed by high performance liquid chromatography and was found to yield terephthalic acid in 90% yield at 93% conversion of p-toluic acid.
