摘要
苯一步氧化制苯酚 ,是有机物氧化合成中富有挑战性的研究课题之一。该文着重论述了在Fe ZSM- 5及其一系列沸石催化剂上 ,应用氧化亚氮作为氧化剂使苯直接氧化制苯酚的研究进展。这一系列催化剂体系的特殊之处在于通过氧化亚氮在沸石分子筛上的分解获得具有催化活性的 α-氧。详细讨论了在沸石分子筛上形成特殊结构的铁氧化物作为催化活性中心这一观点。由于这种催化体系对苯直接氧化制苯酚的反应有着很高的选择性 ,因此 。
One step oxidation of benzene to phenol has been a challenging subject in organic synthesis. In this review, the focus is on the recent advances in gas-phase catalytic oxidation over zeolites using nitrous oxide as oxidant. The remarkbleness of this catalyst system lies in catalytic alpha-oxygen that is got from N2O decomposed over zeolites. The specific structure of Fe-containing active sites and the mechanism of the reaction were considered. This process of one step oxidation of benzene to phenol over FeZSM-5/N2O seems to be quite promising and promotes the development of new ecologically safe technologies for organic synthesis.
