苯酚羟基化合成二酚催化剂的研究进展

Research progress on catalysts for hydroxylation of phenol to dihydroxybenzene

邻苯二酚和对苯二酚都是重要的化工原料和中间体。在催化剂作用下,以H2O2为氧化剂,苯酚羟基化合成二酚是一条反应条件温和、环境友好的合成路线。介绍了二酚的生产现状,综述了苯酚羟基化合成二酚反应中的催化剂的研究进展,并讨论了它们的制备、性能和应用前景。

Catechol and hydroquinone are important chemical feedstocks and intermediates. In the presence of catalysts, the hydroxylation of phenol with H2O2,which is used as the oxidant, to dihydroxybenzene is a mild and environmentally friendly route. In this paper, the manufacture of dihydroxybenzene was introduced. Research progress relating to catalysts for phenol hydroxylation to dihydroxybenzene was reviewed. The preparation, performance and prospects of catalyst application were discussed.
