NiB/C催化剂用于硝基苯加氢制备对氨基苯酚的研究
Preparation of Hydrogenation of Nitrobenzene to p-Aminophenol Using NiB/C Catalyst
摘要
Abstract
Supported amorphous alloy NiB/C was used as catalyst, and zinc sulfate solution was used as acidic medium in the preparation of catalytic hydrogenation of nitrobenzene to p- aminophenol. The effect of reaction temperature, reaction pressure, reaction time, mass of NiB/C catalyst and zinc sulfate on the reaction were studied, the range of reaction conditions of higher selectivity of p- aminophenol was obtained. The better experimental program was determined through the establishment of the orthogonal experiment which has five factors and four levels: reaction temperature is 120 ℃, reaction pressure is 0.1 MPa, reaction time is 3 h, the catalyst addition is 3 g, zinc sulfate addition is 4 g. The results show that the conversion rate of nitrobenzene is 86. 78%, the selectivity of р- aminophenol and aniline are 15. 62% and 76. 02%respectively.关键词
