A catalyst mixture containing a titanium zeolite and a supported gold- containing catalyst is highly selective and productive for transforming olefins to epoxides in the liquid-phase reaction of an olefin, hydrogen, and oxygen. This is particularly surprising because neither titanium zeolite nor the supported gold-containing catalyst alone is effective in olefin epoxidation.
Cette invention concerne un mélange catalytique renfermant un zéolite de titane et un catalyseur supporté contenant de l'or, qui est hautement sélectif et permet de transformer à fort rendement des oléfines en époxydes dans la réaction en phase liquide d'une oléfine, d'hydrogène et d'oxygène. Ce résultat est d'autant plus surprenant que ni le zéolite de titane, ni le seul catalyseur supporté contenant de l'or ne peuvent à eux seuls permettre d'aboutir à une époxydation des oléfines.
