硝基苯催化氢化制备对氨基苯酚

PREPARATION OF p-AMINOPHENOL BY CATALYTIC HYDROGENATION OF NITROBENZENE

硝基苯经催化氢化、转位制备对氨基苯酚（１）。硝基苯转化率９０％，１选择性达８０％。

Using Pd-Co/C catalyst, p-aminophenol was prepared by catalytic hydrogenation of nitrobenzene. The factors, such as catalysts, sulfuric acidconcentration and surfactants which influence the reaction, were studied. Under the optimum conditions, the conversion of nitrobenzene was 90%, selectivity of p-aminophenol was 80%.
