  • Method of preparing epoxidation catalysts
    Patent number: 9433925
    Abstract: A method of preparing epoxidation catalysts is disclosed. The method comprises: (a) adding an inorganic siliceous solid to a column to produce a solid-filled column; (b) adding to the solid-filled column a solution comprising titanium tetrachloride and a hydrocarbon solvent to produce a titanium tetrachloride-impregnated solid; and (c) calcining the titanium tetrachloride-impregnated solid at a temperature from 500° C. to 1000° C. to produce the catalyst. The inorganic siliceous solid has a pore volume of at least 0.8 cm3/g.
