Hydrogenation properties of p-chloronitrobenzene (CNB) have been studied over alumina, zirconium dioxide and titania prepared by different ways supported platinum catalysts in ethanol at 303K and atmospheric pressure. Pt/TiO 2 catalyst exhibits good catalytic activity and selectivity of p-chloroaniline (CAN). The conversion of p-CNB is over 99% and p-CAN is main product on the hydrogenation...
The effect of rare earths (Sm, Pr, Ce, Nd, and La) on the hydrogenation properties of chloronitrobenzene (CNB) over Pt/ZrO2 catalyst was studied in ethanol at 303 K and normal pressure. The results show that the hydrogenation of CNB can be carried out over Pt/ZrO2 catalyst. The order of the hydrogenation rates of CNB is p>m>o, and the yield of chloroaniline (CAN) is p>o>m. The specific...
