Abstract
In this paper, two-step method was used to synthesize 5,10,15,20-tetraphenyl-21H,23H-porphine vanadium(IV) oxide (VOTPP) and toluene catalytic oxidation was explored. The result showed that this catalyst led to benzoic acid as the main product and successfully simulated the reaction of toluene oxidation with the catalytic center of P-450 enzyme. Through testing the reaction conditions including used catalyst amount, temperature, pressure, and reaction time, the optimum reaction conditions were: 0.3 g VOTPP in 100 cm3 of toluene, 145 °C, 0.8 MPa, and 4 h. The conversion of toluene was 23.0% and the selectivity of benzoic acid could reach 86.0%. Its benefits lie in no solvent, mild reaction conditions, and no toxic acidic waste, making toluene oxidation a green process.
