<p>In a method for producing chlorine comprising oxidizing hydrogen chloride present in a gas containing the hydrogen chloride using a gas containing oxygen in the presence of a catalyst, an improvement which comprises conducting the oxidation of the hydrogen chloride in a reaction region comprising at least two catalyst-packed layers connected in series and carrying out the temperature control of at least one reaction region using a heat exchange system is disclosed. This method enables the inhibition of formation of excess hot spots and effective utilization of the catalyst-packed layers, which results in maintaining stable activity of the catalyst and in the production of chlorine in high yield with good stability.</p>
