Preparation of Hierarchical TS-1 Zeolite and the Research on Epoxidation of Catalyzing of 1-octene
A series of hierarchical TS-1 zeolite were prepared using P123 as an auxiliary agent.The resultant samples were characterized by using IR,UV-Vis,XRD,BET and ICP were evaluated as cata-lysts for the epoxidation of 1-octene with hydrogen peroxide.The results reveal that all the hierarchical TS-1 zeolite have the typical MFI structure and their morphology change somewhat with the different P123.The sample synthesized with P123(MW=5 800)could efficiently convert 1-octene to the corre-sponding epoxide with a high yield of 56.05%and high epoxide selectivity of 59.2%under an opti-mized reaction condition.
