| Abstract: | Poly（N-vinyl-2-pyrrolidone）-stabilized Ru/Pt colloidal （PVP-2Ru/1Pt） were prepared in ethanol- water mixed solvents with ethanol as reductant. PVP-2Ru/1Pt was used as a catalyst for the selective hydro- genation of m-chloronitrobenzene （m-CNB） and p-chloronitrobenzene （p-CNB）. The influence of substrate concentration, catalyst concentration, reaction temperature on the hydrogenation was investigated. Under the conditions at 30 ℃and 0. 1 MPa of hydrogen, the average rate of m-CNB and p-CNB reached 0. 0545 and 0. 0542 s^-1 and the conversion was 100%. The selectivity of m-chloroaniline and p- chloroaniline was 99.3 and 〉99.9% respectively. |
