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 of preparing p-aminophenol by electrochemical reduction of nitrobenzene in a fixed-bed electrochemical reactor was studied.The reactor design was carried out on the fixed-bed electrochemical reactor model established in [7, 8] The molar selectivity β≥80%, current efficiency η_i≥75% and apparent current density i≥1500A / m ~ 2 were measured in this study. In this study, nitrobenzene electrochemical reduction in a fixed-bed electrochemical reactor Preparation of p-aminophenol process industrialization has laid an important theoretical basis.
