A method is disclosed to produce chlorine dioxide from sodium chlorate by reacting the chlorate with HCl. The method comprises forming in a reaction vessel an aqueous reaction medium containing at least about 5.5 moles per liter of the sodium chlorate, sufficient HCl to provide an acid normality of at least about 0.002, and sufficient sodium chloride to saturate the reaction medium; boiling the reaction medium at a temperature of up to about 100.degree. C; and withdrawing a mixture containing chlorine dioxide gas, chlorine gas and water vapor from the reaction vessel.
