已经考虑使用沸石作为选择性氧化反应的催化剂。最近对一氧化二氮芳烃气相氧化羟基化的研究给予了特别关注。简单的反应（即在含铁 ZSM-5 沸石上将苯氧化为苯酚）获得了最佳结果。它的选择性接近 100%，苯转化率为 25-30%。芳烃羟基化这一有希望的方向的进一步进展可以为有机合成提供新的高效技术。讨论了一氧化二氮作为氧化剂的特性和反应机理。
The use of zeolites as catalysts for selective oxidation reactions has been considered. Particular attention has been paid to recent studies of a gas-phase oxidative hydroxylation of aromatics by dinitrogen monoxide. The best results were obtained for a simple reaction, the oxidation of benzene to phenol over Fe-containing ZSM-5 zeolites. It proceeds with nearly 100% selectivity at 25–30% benzene conversion. Further progress in this promising direction, the hydroxylation of aromatics, can provide new efficient technologies in organic synthesis. Peculiarities of dinitrogen monoxide as an oxidant and the reaction mechanism are discussed.
