A method for activating a catalyst for chlorine production used in a reaction for oxidizing hydrogen chloride with oxygen, including the step of bringing a catalyst for chlorine production having decreased activity into contact with a basic liquid, and a method for producing chlorine by oxidizing hydrogen chloride with oxygen in the presence of a catalyst for chlorine production activated by the above method are provided. The basic liquid used preferably has a pH of 8 or more, and is preferably an aqueous solution in which an inorganic base is dissolved. The catalyst for chlorine production is preferably a catalyst containing ruthenium oxide. |
