【摘要】 制备了聚合物硼氢阴离子交换树脂（BER）、活性碳钯（Pd／C）和聚合物负载金属钯（Pd／D411）等催化剂，对各种取代的邻硝基苯酚进行了催化氢化还原反应。比较了上述三种催化剂对各种底物的催化活性的影响。研究结果表明：当邻硝基苯酚的苯环上取代基不同或取代基的位置不同时，它们被还原的难易程度不同。另外，催化剂载体对催化剂的性能也有很大影响。更多还原

【Abstract】 Borohydride exchange resin(BER), active carbon supported palladium (Pd/C)and polymer supported palladium(Pd/D411 ) were synthesized and used as catalysts for hydrogenation of various substituted o -nitrophenols. The activities of abovementioned 3 kinds of catalysts for the hydrogenation of various substrates were studied. The results showed that the yields of hydrogenation products were varide with the kind and postion of substituting group in the benzene ring of substituted o nitrophenols. In addition, the properties of catalysts were varied with the polymer supports.更多还原
