A method for the production of a solid on the basis of silicic acid and titanium and the use of this solid material, in particular for the epoxidation of olefins

摘要

Method of obtaining solid particle comprising silica, titanium, characterized in that it comprises the placing in contact with a suspension, containing an initial amorphous silica particles in aqueous medium at basic ph with trifluoride of titanium (tif3) or tetrafluoride of titanium (tif4), in a quantity of 0,1 to 10% by weight of titanium (ti) with respect to the weight of silica.
