Process for the epoxidation of olefinic compounds and catalysts used therein

摘要: A process for the epoxidation of olefinic compounds comprising reacting said with hydrogen peroxide introduced as such or produced by substances under reaction conditions, in presence synthetic zeolites containing titanium atoms corresponding to general formula: x TiO.sub.2 (1-x) SiO.sub.2 wherein is range from about 0.0001 0.04, and optionally, one more solvents, at a temperature 0° 150° C. pressure 1 100 atm. The are treated alkaline before and/or during their use reaction, alternatively acid neutralized compound X-Si-(R) 3 where X selected Cl, Br, I, ##STR1## an imidazolyl group R alkyl, aryl alkylaryl group.
