5.5%Ti-MSU molecular sieve catalyst was prepared by liquid phase impregnation method. The sam-ple was characterized by X-ray diffraction and N2 adsorption-desorption. With cumene hydroperoxide ( CHP) ,1-bu-tene as raw material,the influence of the process conditions of 5.5%Ti-MSU catalyst on epoxybutane had been in-vestigated. The conversion of CHP was 81.2%,1,2-epoxybutane ( BO) selectivity was 60.2%, benzyl alcohol ( DMBA) selectivity was 87.2%, when the optimum reaction conditions was 100℃ catalyst bed,3.0 MPa reactivity pressure,10∶1 1-butylene/CHP molar ratio and 2h-1 space velocity of CHP.
