Abstract: Titanosilicate catalyst is used in the oxidation reactions such as allylchloride epoxidation, phenol hydroxylation, Cyclohexanone ammoximation. During the reaction the catalyst is deactivated which further decrease in the efficiency of the oxidation reactions. The present invention provides a method for an efficient regeneration of catalyst titanosilicate catalyst at low temperature below 100° C. using a gaseous mixture containing ozone, without isolating the catalyst from the reactor system.

Abstract translation: 氧化反应中使用钛硅酸盐催化剂，例如烯丙基氯化物环氧化，苯酚羟基化，环己酮氨基肟化。 在反应期间，催化剂失活，进一步降低了氧化反应的效率。 本发明提供了一种使用含有臭氧的气体混合物在低于100℃的低温下有效再生催化剂钛硅酸盐催化剂的方法，而不将催化剂与反应器系统分离。
