Title:

METHOD FOR PRODUCING CARBONYL HALIDE

Document Type and Number:

WIPO Patent Application WO/2022/172744

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide an efficient method of producing a carbonyl halide for a halogenated methane used. A method for producing a carbonyl halide according to the present invention is characterized by comprising: a step for preparing a mixed gas that contains oxygen and a halogenated methane having one or more halogeno groups selected from the group consisting of chloro-, bromo-, and iodo-; and a step for causing the mixed gas to flow and irradiating the flowing mixed gas with high-energy light.
