摘要
研究了在固定床电化学反应器内硝基苯电化学还原制备对氨基苯酚的过程.采用文献[7,8]建立的固定床电化学反应器模型对该反应过程进行了反应器设计.实验测得该反应的摩尔选择性β≥80%,电流效率η_i≥75%,反应器表观电流密度i≥1500A/m^2.本研究为固定床电化学反应器内硝基苯电化学还原制备对氨基苯酚过程工业化奠定了重要的理论基础.
The process,electrochemical reduction of nitrobenzene to produce p-amino-phenol in a packed bed electrochemical reactor, is investigated. The reactor is desiged with the aid of the reactor model established in the literature [7,8] of the study. Applying this model, the authors calculate the model of the reduction of nitrobenzene for p-aminophenol process and compare with the experiments. The experimental results show that this process can be operated at acurrent density i≥2000A/m2, selectivity β≥80.0%, and current effenct ηi75.0%. This study provides a very important basis for the industrialization of the studied process.
