    • The present invention provides a catalyst containing titanium in bonded form, non-crystalline silicon dioxide and at least one crystalline silicate phase which has a zeolite structure, wherein the non-crystalline silicon dioxide is applied to at least one of the crystalline silicate phases which have a zeolite structure and wherein at least one of the crystalline silicate phases which have a zeolite structure contains silicon-carbon bonds with which non-hydrolytically separable organic groups R are bonded to silicon. Furthermore, the present invention provides a process for preparing this catalyst and a process for producing an epoxide from a compound which contains a carbon-carbon double bond (preferably from propene) comprising reacting the compound which contains a carbon-carbon double bond with hydrogen peroxide in the presence of the catalyst according to the invention.
    • 本发明提供一种催化剂,其含有键合形式的钛,非结晶二氧化硅和至少一种具有沸石结构的结晶硅酸盐相,其中将非结晶二氧化硅施加到至少一个结晶硅酸盐相,其具有 沸石结构,并且其中具有沸石结构的结晶硅酸盐相中的至少一个含有硅 - 碳键,非水解可分离的有机基团R与硅键合。 此外,本发明提供了一种制备该催化剂的方法和由含有碳 - 碳双键(优选丙烯)的化合物制备环氧化物的方法,包括使含有碳 - 碳双键的化合物与过氧化氢 在根据本发明的催化剂的存在下。
