ABSTRACT:
Epoxidation catalyst based on titanium zeolite in the form of extruded granules. Use of this catalyst in the synthesis of epoxides, preferably 1,2-epoxy-3-chloropropane or 1,2-epoxypropane, by reacting an olefinic compound, preferably allyl chloride or propylene, with a peroxide compound, preferably hydrogen peroxide. Process for the preparation of an epoxide, preferably 1,2-epoxy-3-chloropropane or 1,2-epoxypropane, by reacting an olefinic compound, preferably allyl chloride or propylene, with a peroxide compound, preferably hydrogen peroxide, in the presence of the aforementioned catalyst.
