The invention relates to a process for the production of chlorine dioxide. Specifically, the invention relates to a process for the production of chlorine dioxide, by which sulphuric acid can be efficiently mixed into the reaction mixture. The process apparatus comprises a reaction vessel (1) operating in reduced pressure, in which alkali metal chlorate is reduced in acidic conditions. The reaction vessel (1) is equipped with a recirculation line (2) of the reaction mixture, comprising a circulation pump (3) and, downstream after the pump, a heat exchanger (4). The process is characterized in that the sulphuric acid is fed into the recirculation line (2) before the said circulation pump, or into the circulation pump (3). |
