    • A method of synthesizing an olefin epoxidation catalyst comprises the step of treating a porous crystalline aluminosilicate material having an X-ray diffraction pattern including d-spacing maxima at 12.4+/-0.25, 6.9+/-0.15, 3.57+/-0.07 and 3.42+/-0.07 Angstrom, such as MCM-22, with a dealuminating agent under conditions effective to remove framework aluminum from the material and produce a dealuminated product. The dealuminated product is then treated with a titanium-containing material under conditions effective to insert titanium into the dealuminated product and produce a titanium-containing, dealuminated catalyst composition. The resultant catalyst is useful in the epoxidation of olefins, such as propylene and cyclohexene, and hydrogen peroxide and organic hydroperoxides.
    • 合成烯烃环氧化催化剂的方法包括以下步骤:处理多晶结晶硅铝酸盐材料,该多晶结晶硅铝酸盐材料具有包含d间距最大值的X射线衍射图,为12.4 +/- 0.25,6.9 +/- 0.15,3.57 +/- 0.07和3.42 +/- 0.07埃,例如MCM-22,在有效从材料中除去骨架铝并产生脱铝产品的条件下用脱铝剂。 然后在有效地将钛插入脱铝产品中并且生产含钛脱铝催化剂组合物的条件下,用含钛材料处理脱铝产品。 所得催化剂可用于烯烃的环氧化,如丙烯和环己烯,以及过氧化氢和有机氢过氧化物。
