%X 1-Butylene epoxidation was catalyzed by microporous titanosilicate molecular sieves TS-1 synthesized by different methods and mesoporous titanosilicate molecular sieves Ti-HMS, using dilute hydrogen peroxide solution as oxidant. The effect of the Si/Ti molar ratio of the catalyst TS-1 and Ti-HMS on their performance was investigated. Conventional TS-1 has smaller crystal size and higher activity than that of TS-1 synthesized by using TPABr as template or the method of gas-solid phase. The TS-1 synthesized by using TPABr as template exhibits the highest selectivity to 1, 2-epoxybutane (BO). With the increase of Ti content in molecular sieves, the conversion of H_2O_2 increases. The catalytic activity of mesoporous Ti-HMS is lower than that of TS-1, and large amount of H_2O_2 is decomposed in 1-butylene epoxidation. The primary reason for low activity of Ti-HMS in 1-butylene epoxidation is that Ti-HMS has poorer hydrophobicity property than TS-1.
