In a particularly advantageous manner, hydrogen chloride is oxidized to chlorinewith oxygen in the presence of a salt melt, if a salt melt which contains metal salts, salt depressing the melting point and if appropriate promoters is used, temperatures between 300 and 600°C are employed, the salt melt is dispersed in the gas containing hydrogen chloride and oxygen in such a way that contact timesof 0.01 to 100 seconds result, the reaction gases are cooled and hydrogen chloride and water are separated out of the reaction mixture, the reaction gases substantially freed from most of the water and some of the hydrogen chloride arefreed from residual water using sulphuric acid, and the gas mixture then essentially containing chlorine, hydrogen chloride and oxygen is compressed to 2to 10 bar, the chlorine is liquefied by cooling and the remaining, essentially oxygen-containing gas is recycled in whole or in part to the reaction zone.
