摘要： The invention relates to a method for producing chlorine using a multi-stage oxidation, by the thermal reaction of hydrogen chloride with oxygen using catalysts, or by the non-thermally activated reaction of hydrogen chloride with oxygen. In said method, the gaseous mixture that is produced during the reaction and that consists of the target products chlorine and water, non-converted hydrogen chloride and oxygen, in addition to further minor constituents, in particular carbon dioxide and nitrogen is a) cooled to condense hydrochloric acid and b) the aqueous solution of hydrogen chloride (hydrochloric acid) thus produced is isolated from the gaseous mixture. The invention is characterised in that: c) the isolated hydrochloric acid is at least partially fed to an electrochemical oxidation, in which at least part of the aqueous hydrochloric acid is oxidised to chlorine; d) the chlorine gas that accumulates in step (b) is optionally added to the gaseous mixture that accumulates in step (c); e) the residual water in steps (b) and (d) is removed, in particular by washing with sulphuric acid; and f) oxygen and optionally minor constituents are eliminated from the chlorine-rich gaseous mixture that is thus produced.
