纳米尺寸的氢化钠对硝基苯的还原反应

Reduction of nitrobenzene by sodium hydride of nanometer size

用纳米尺寸的氢化钠对硝基苯进行了还原，主要产物为氧化偶氮苯，收率明显优于在相同条件下使用工业氢化钠所得的结果。考察了反应参数对硝基苯转化率及产物组成的影响。

Nitrobenzene can be reduced by sodium hydride of nanometer size leading to azoxybenzene as the main product in fairly good yield. In comparison,the commercial sodium hydride gives only very low or eyen negligible yield under the same reaction con ditions. The effect of reaction parameters on the nitro benzene conversion and product composition has been studied.
