【摘要】 研究了硝基苯催化加氢制备对氨基苯酚的反应。通过实验发现，不同的反应介质、添加剂、载体和催化剂的制备方法对对氨基苯酚的收率有很大的影响。在硫酸介质中两次性加入硝基本对反应最有利。ＡＩＢｒ３作添加剂时，可以提高目标产物的收率。改性的γ－Ａｌ２Ｏ３作载体时，对氨基苯酚的收率可达７４％。更多还原

【Abstract】 The synthesis of para-aminophenol （PAP） from nitrobenzene isstudied by examining the effects of different reaction media, promoters,supports, and preparation methods of catalysts on the catalyst activity. Theresults show that tile aqueous solution of sulfuric acid is the most suitablereaction medium, A1Br3 is an effective promoter and Pt/modified γ-Al₂O₃ isa promising catalyst for this reaction.更多还原
