摘要： 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.

摘要： The invention relates to a process for the oxidation of carbon-containing organic compounds where the said compounds have at least one bond with a bond order >1, wherein an oxidizing of these carbon-containing organic compounds to be oxidized is performed with electrochemically generated C—O—O oxidizing agents, in particular peroxodicarbonate. Also described is the use of C—O—O oxidizing agents generated electrochemically from carbonate, in particular peroxodicarbonate, as oxidizing agents for the oxidation of carbon-containing organic compounds, in particular carbon-containing organic compounds where the said compounds have at least one bond with a bond order >1. Finally, an arrangement for the oxidation of carbon-containing organic compounds is provided, comprising a first unit for the electrochemical preparation of C—O—O oxidizing agents generated electrochemically from carbonate, in particular peroxodicarbonate, and a second unit for the oxidizing of the carbon-containing organic compound with the C—O—O oxidizing agent generated electrochemically from carbonate, in particular peroxodicarbonate. In this case, these two units are connected to one another in such a way that an ex situ generated oxidizing agent can be fed to the second unit.

摘要： A fluidized reaction method for synthesizing propylene oxide by gas phase epoxidation of propylene and hydrogen peroxide relates to a microspherical alkali metal ion modified titanium silicalite zeolite TS-1 catalyst applicable to the reaction method, and a preparation method thereof. A gas-solid phase fluidized epoxidation method refers to a gas phase epoxidation method in which the raw materials of propylene and hydrogen peroxide are directly mixed in the gas phase under normal pressure and temperature above 100° C. and the feed gas enables the titanium silicalite zeolite TS-1 catalyst to be fluidized in an epoxidation reactor. A catalyst applicable to the reaction method is a microspherical alkali metal ion modified titanium silicalite zeolite TS-1 catalyst which has the main characteristic that alkali metal cations are reserved on the titanium silicalite zeolite.
