  • Patent number: 11492336
    Abstract: The present invention provides: a method for producing an epoxyalkane capable of obtaining an epoxide in a high yield while attaining a high olefin conversion rate and a high selectivity for epoxides even when an olefin includes a long carbon chain, and a solid oxidation catalyst. The method for producing an epoxyalkane of the present invention comprises reacting an olefin with an oxidant in the presence of a solid oxidation catalyst, wherein the solid oxidation catalyst comprises a transition metal and a carrier that supports the transition metal, and the carrier is a composite of a metal oxide with a phosphonic acid.

    Abstract: The present invention provides: a method for producing an epoxyalkane capable of obtaining an epoxide in a high yield while attaining a high olefin conversion rate and a high selectivity for epoxides even when an olefin includes a long carbon chain, and a solid oxidation catalyst used in the method. The method for producing an epoxyalkane of the present invention comprises reacting an olefin with an oxidant in the presence of a solid oxidation catalyst, wherein the solid oxidation catalyst comprises a transition metal and a carrier that supports the transition metal, and the carrier is a metal oxide having a silyl group represented by the following general formula (1): R1R2R3Si—??(1) wherein R1, R2, and R3 are each independently a single bond, a hydrocarbon group, a halogenated hydrocarbon group, an alkoxy group, or a halogen, and at least one of R1, R2, and R3 is a hydrocarbon group having 3 or more carbon atoms or a halogenated hydrocarbon group having 3 or more carbon atoms.
