Abstract
A process for producing an aqueous hypochlorous acid solution reacts droplets of an alkali metal hydroxide solution containing greater than 50 percent by weight of the alkali metal hydroxide with chlorine gas. 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.degree. C. and about -5.degree. C. to produce the aqueous hypochlorous acid solution. The process of the invention results in increased yields of hypochlorous acid and provides an economic basis for increased production capacity. The aqueous hypochlorous acid solutions produced are highly pure and as a result have significantly improved stability.
