Abstract: The first aspect of the present invention is intended to provide a method for producing an oxidation reaction product of the hydrocarbon or a derivative thereof efficiently using hydrocarbon or a derivative thereof as a raw material. In order to achieve the above object, the first aspect of the present invention provides a method for producing an oxidation reaction product of a hydrocarbon or a derivative thereof. The method includes the step of irradiating a reaction system with light in the presence of a raw material and a chlorine dioxide radical. The raw material is hydrocarbon or a derivative thereof, the reaction system is a reaction system containing an organic phase, and the organic phase contains the raw material and the chlorine dioxide radical. In the step of irradiating a reaction system with light, the raw material is oxidized by the light irradiation to generate an oxidation reaction product of the raw material.
