Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.

同时结合Ti-ZSM-5催化选择性氧化苯乙烯反应的产物分布结果，提出苯乙烯环氧化反应可能是通过金属有机环机理进行；Ti-ZSM-5同时具有催化环氧化和酸催化两种功能，其骨架钛可催化苯乙烯环氧化生成环氧苯乙烷，而骨架钛和骨架铝等可提供Lewis酸位使环氧苯乙烷迅速发生重排生成苯乙醛从而使其成为反应的主要产物，同时还可发生加成以及碳碳键的裂解等副反应：Ti-ZSM-5也提供Bronsted酸位，它也是生成加成产物的活性中心。
