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
