Abstract

A procedure for the production of chlorine dioxide, chlorine, and an alkali metal chloride, in which an aqueous solution of an alkali metal chlorate and concentrated hydrochloric acid are continuously introduced into a single-pot vessel that acts as a generator-evaporator-crystallizer and contains an aqueous reaction solution, maintained at a temperature of 25-90ºC and a pressure of 20 to 400 mm absolute mercury, to form a reaction solution of approximately 0.05 to 1.9 N in hydrochloric acid, of 0.5 at 5 M in alkali metal chlorate and saturated with alkali metal chloride, maintaining a substantially constant volume of the reaction solution by evaporation and separation of water vapor in mixture with chlorine dioxide and chlorine from said unilocular vessel and separating the chloride solid alkali metal formed in said reaction solution of said unilocular vessel.
