| 摘 要： | 对N i-B/S iO2非晶态催化剂在二硝基苯加氢制苯二胺反应中的催化活性进行了研究。研究表明,该催化剂具有很高的催化活性,性能优于R aney N i催化剂,转化率可以达到100%,选择性达到98.6%,晶化导致催化剂失活。载体能提高催化剂的分散度,使催化剂的活性比表面积增大。

| Abstract: | Ni-B/SiO_2 amorphous catalyst was explored in hydrogenation of dinitrobenzene to dianiline. In comparison with other Ni-based catalysts, such as Raney Ni,Ni-B/SiO_2 amorphous catalyst exhibited higher activity and better selectivity for dianiline.The silica support could disperse the catalyst, increase the surface active area of the catalyst. |

| Keywords: | amorphous catalyst dinitrobenzene catalytic hydrogenation dianiline |
