| 摘要 |
The invention concerns a catalyst based on titanium zeolite in the form of extruded granules and the use of said catalyst in the synthesis of oxirannes, preferably 1,2-epoxy-3-chloropropane or 1,2-epoxypropane, by reaction between an olefinic compound, preferably allyl chloride or propylene, with a peroxidized compound, preferably hydrogen peroxide. The invention also concerns a method for making an oxiranne, preferably 1,2-epoxy-3-chloropropane or 1,2-epoxypropane, by reaction between an olefinic compound, preferably allyl chloride or propylene, and a peroxidized compound, preferably hydrogen peroxide, in the presence of said catalyst.
