Abstract:
An epoxidation process comprising contacting an organic hydroperoxide with an olefin in the presence of a catalyst obtained by a method comprising the steps of:(a) impregnating an inorganic siliceous solid with a titanium source selected from the group consisting of:(1) a solution of a titanium halide in a non-oxygenated hydrocarbon solvent; and(2) a vapor stream of titanium tetrachloride; said inorganic siliceous solid having a surface area greater than 1100 m.sup.2 /g;(b) calcining the impregnated siliceous solid to form the catalyst composition; and(c) optionally, heating the catalyst in the presence of water;said method being characterized by the substantial exclusion of water until at least after step (a) is completed.
