四元骨架镍在脂肪族低碳硝基化合物催化氢化还原反应中的应用

Application of Four-Element Raney Ni in Catalytic Hydrogenation of Aliphatic Low-carbon Nitro Compounds

以四元骨架镍（Ni-Al-Mo-Fe）为催化剂,脂肪族低碳硝基化合物经催化氢化还原反应合成了相应的氨基化合物。并探讨了其组成、粒径对催化氢化还原反应的影响。结果表明：100目-150目Ni-Al-Mo-Fe（Ni%〉90%）为最优组成,其催化氢化收率为95%,转化率均大于99%。

Aliphatic low-carbon nitro compounds were catalytic hydrogenated using four-element Raney Ni（ Ni-Al-Mo-Fe） as the catalyst. The effect of compostion and size of the catalyst to the hydrogenation was investigated. The results showed that 100 mesh - 150 mesh Ni-Al-Mo-Fe（ Ni% 90%） was the most suitable catalyst for the hydrogenation with the yields of 95%,and the conversion rates were more than 99%.
