Abstract
Direct hydroxylation of benzene to phenol with hydrogen peroxide over catalysts prepared by the V(V) impregnated on b-zeolite was examined under microwave irradiation. It was found that the V(V)/b-zeolite catalyst gave the highest activity than Cu(II), Co (II)/b-zeolite at same experimental condition. Various techniques (XRD and BET surface area) were employed to characterize the catalysts. The influence of some operating variables, such as the amount of hydrogen peroxide used, the amount of catalyst used and the reaction time on the conversion of benzene, were studied to obtain the optimal reaction conditions under microwave irradiation. A benzene conversion of 14.7 % with a selectivity of 100 % was obtained when the 5 % loading amount of V(V) under optimized conditions.
