负载型Ni/C催化对硝基酚加氢制备对氨基酚

Synthesis of p-Aminophenol by Catalytic Hydrogenation of p-Nitrophenol with Ni/C Catalyst

以Ni/C为催化剂,催化对硝基酚加氢制备对氨基酚。优化了工艺条件,选用10%Ni/C作为催化剂,研究了温度,压力,催化剂加入量对反应的影响。在100℃,2 MPa下,对氨基酚的选择性大于99%。

In this paper, p - aminophenol was synthesized by catalyzing the hydrogenation of p - nitrophenol with Ni/C. 10 % Ni/C was chosen to optimize the technological factor, and the effect of temperature, pressure and the amount on catalyst were also be conaidered. As a conclusion, the selectivity to p - aminophenol was more than 99% under 2 MPa at 100℃.
