ABSTRACT:
Highly active and selective epoxidation catalysts are prepared by combining high surface area silica support or the like, having surface area greater than 1100 m.sup.2 /g, with a titanium source. The titanium source is a non-oxygenated hydrocarbon solution of a titanium halide or a vapor stream of titanium tetrachloride. The impregnated support it then calcined at an elevated temperature (preferably, in a substantially oxygen-free atmosphere), and, optionally, reacted with water and/or silylated. The resulting materials are highly active heterogeneous epoxidation catalysts for the reaction of olefins to with organic hydroperoxides.
