摘　　要：将2-硝基苯酚溶于甲醇,置于反应釜中,加入Raney-Ni催化剂,在温度62℃、0.9MPa的氢气压力下,反应90～100分钟,制备2-氨基苯酚。Preparation of 2 - amino phenol by catalytic hydrogenation of 2 - nitro phenol, and effect of process parameters on the catalytic hydrogenation reactions was studied. The condition for the hydrogenation was mild, the pressure less than 1.0MPa, the temperature below 62℃, the reaction time 90 - 100min, the yield of 2 - amino phenol could reach 98.7%.
