ABSTRACT The present invention provides a process for the continuous production of chlorine dioxide by the reaction of hydrochloric acid with an alkali metal chlorate solution, which is obtained by means of an electrolysis plant from a chlorate solution containing alkali metal chloride circulating in the process, together with cathodically-formed hydrogen, in a cascade reactor with the introduction of air, wherein the reaction of the alkali metal chlorate solution with the hydrochloric acid is carried out under reduced pressure and chlorine gas separated off from the reaction product is reacted with the cathodically-formed hydrogen with the introduction of external chlorine gas to give the required amount of hydrochloric acid. The present invention also provides a device for carrying out this process, comprising at least one chlorate electrolysis plant, a cascade reactor, a separation column and a hydrochloric acid synthesis furnace, which are connected with one another by means of pipes according to the manner of operating the process, wherein a valve is provided in the air inlet pipe of the reactor, which valve is regulated corres- ponding to the pressure at the product outlet of the reactor.
