The reaction produces a gaseous mixture of dichlorine monoxide, chlorine, hypochlorous acid vapor and water vapor, and solid particles of alkali metal chloride. The solid particles of alkali metal chloride are separated and the gaseous mixture condensed at a temperature in the range of from about -33 ·C and about -5 ·C to produce the aqueous hypochlorous acid solution.
