In the continuous production of chlorine dioxide wherein an alkali metal chlorate solution is reacted with hydrochloric acid in a reactor through which an air stream is passed countercurrent to the alkali metal chlorate solution, and there discharged from the reactor chlorine dioxide and alkali metal chloride solution, the improvement which comprises including chlorine gas in the air stream, thereby permitting the overall efficiency of the process to be increased at a given content of chlorine dioxide in the gas discharged from the reactor. |
