摘要： 用水热合成法和浸渍法制备Ti-MSU分子筛催化剂，采用热重分析、X射线衍射、N2吸附-脱附、红外光谱对催化剂样品进行表征，并考察两种制备方法所得催化剂在1-丁烯环氧化反应中的催化性能。结果表明，Ti物种是催化剂活性组元，在钛负载量相同(质量分数5.5%)时，浸渍法比水热法制备的Ti-MSU催化剂活性高。
Abstract: Ti-MSU molecular sieve catalysts were prepared by hydrothermal synthesis and impregnation method, respectively. The samples were characterized by TG, X-ray diffraction, N2 adsorption-desorption and FT-IR. The epoxidation performance for 1- butylene was studied. The results show that the Ti atom species are the catalyst active component and the activity of Ti-MSU catalyst with 5.5w% Ti by impregnated method is much higher than the hydrothermal one.
