摘要
经过研究发现,我们对乙醇中的硝基苯酚加氢反应进行了调查,并使用Ni/硅藻土作为催化剂。我们研究了反应温度、压力和时间等因素对该加氢反应的影响。结果显示,最佳条件是:催化剂浓度在0.9~1.2%之间;保持反应温度在95~105℃范围内;维持氢气压力在1.5~1.8 MPa之间;并且需要将反应时间控制在90分钟以内。
We investigated the hydrogenation of nitrophenol in ethanol and used Ni/diatomaceous earth as the catalyst. The effects of reaction temperature, pressure and time on the hydrogenation reaction were studied. The results show that the optimal conditions are: the concentration of catalyst is between 0.9 and 1.2%;Keeping the reaction temperature in the range of 95~105˚C;Maintaining the hydrogen pressure between 1.5~1.8 MPa;and the response time should be controlled within 90 minutes.
