对硝基苯酚催化加氢研究进展

摘要

p-Aminophenol is a commercially important chemical and medical intermediate. Among the preparation routes of p-aminophenol, catalytic hydrogenation of p-nitrophenol to p-aminophenol has some remarkable advantages, such as simple synthesis process, high-quality products and friendliness to environment, therefore this process has a good prospect. This paper reviews the recent research progress of the catalysts used in p-nitrophenol hydrogenation. The preparation of p-aminophenol through the process coupling catalysis and membrane separation is highlighted, and its developmental trend is also discussed.%对氨基苯酚是一种重要的化工和医药中间体,对硝基苯酚催化加氢制备对氨基苯酚具有工艺简单,产品质量高、环境污染小等优点,展现出良好的发展前景.本文就对硝基苯酚催化加氢制备对氨基苯酚所用催化剂的研究进展进行了综述,着重介绍了催化-陶瓷膜分离耦合制备对氨基苯酚新工艺,并对其技术发展作了展望.
