Abstract:
1. In a process for producing an epoxide from a compound containing a carbon-carbon double bond, the improvement comprising reacting the compound containing a carbon-carbon double bond with hydrogen peroxide in the presence of a catalyst comprising, a) titanium in bonded form, b) non-crystalline silicon dioxide and c) at least one crystalline silicate phase having a zeolite structure, wherein the non-crystalline silicon dioxide is applied to at least one of the crystalline silicate phases having a zeolite structure and at least the titanium atoms tetrahedrally incorporated in one crystalline silicate phase, and wherein at least one of the crystalline silicate phases having a zeolite structure contains silicon-carbon bonds binding non-hydrolytically separable organic groups R to silicon, wherein R comprises C 1 to C 12 alkyl.
