A convenient method for improving the conversion and selectivity of aniline to azoxybenzene by adjusting the ratio of silicon to titanium of TS-1 is reported. Over TS-1 (80), aryl anilines are transformed into the corresponding azoxybenzenes in good yields with H2O2 as the oxidant. The effect of different reaction parameters like molar ratio of H2O2 to aniline, solvent and the activity in catalyst recycling has been studied.
Key words： anilines; oxidation; azoxybenzene; H2O2
