Abstract

This paper investigated the microwave assisted liquid phase hydroxylation of benzene to phenol with hydrogen peroxide over V(V)/SiO₂ catalysts prepared by microwave impregnated method. The catalysts were characterized by XRD, N₂ adsorption techniques. The results manifested that the performance of the catalysts was significantly affected by the amount of V(V) loaded onto the SiO₂ and microwave irradiation time. The effects of various reaction parameters, such as the amount of catalyst used, the amount of hydrogen peroxide used and reaction time on the yield of phenol was investigated at room temperature under microwave irradiation. Coupled conventionally heated method gives phenol yield of 11.8 %, the V(V)/SiO₂ prepared by microwave impregnated method gives higher phenol yield of 19.7 % and selectivity of 100 % under microwave irradiation.
