摘　　要：将自制的Ni-B非晶态合金催化剂用于间硝基甲苯催化加氢制备间甲苯胺的反应。考察了加氢条件对间甲苯胺产率的影响。结果表明,制得的Ni-B非晶态合金催化剂具有良好的催化活性;以乙醇为溶剂,催化剂与原料的质量比为1∶5,反应时间为2 h,反应压力为1 MPa,反应温度为100°C,此条件下间甲苯胺产率为99.8%。m-Toluidine was prepared by hydrogenation of m-nitrotoluene in the presence of amorphous Ni-B catalyst, effects of reaction parameters on the yield were studied. The results showed that the home-made amorphous Ni-B catalyst was effective. Under the conditions of re（catalyst） ： m（m-nitrotoluene）= 1 ： 5, alcohol as solvent, reaction time 2 h, reaction pressure 1 MPa and reaction temperature 100℃, the yield of m-toluidine reached 99.8%.
