PROBLEM TO BE SOLVED: To make a mixed gas containing carbon monoxide, phosgene, hydrogen or an organic compound and hydrogen chloride contact with a gas containing oxygen, and selected from carbon monoxide, phosgene, hydrogen or an organic compound in the mixed gas. A method for producing chlorine comprising oxidizing at least one compound and simultaneously oxidizing hydrogen chloride to chlorine, wherein the conversion rate of carbon monoxide, phosgene, hydrogen or an organic compound is high, and the conversion rate of hydrogen chloride to chlorine A method for producing high chlorine is provided. SOLUTION: In the presence of ruthenium and / or ruthenium compound supported on titanium oxide, a mixed gas containing at least one compound selected from the group consisting of carbon monoxide, phosgene, hydrogen and an organic compound and hydrogen chloride is mixed with oxygen. In contact with a gas containing oxygen to oxidize the at least one compound and simultaneously oxidize hydrogen chloride to chlorine. [Selection figure] None |
