    摘要: 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 aluminium 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, with hydrogen peroxide and organic hydroperoxides.
