ABSTRACT:
A process for preparing hypochlorous acid is described in which gaseous chlorine is reacted with an aqueous solution of alkali metal hydroxide in a finely divided mist form at an elevated temperature sufficient to prevent condensation of the gaseous product. Gaseous hypochlorous acid product is immediately separated from the resulting solid alkali metal chloride as it is formed and is then scrubbed with water to form an aqueous hypochlorous acid solution. This solution may be reacted with lime to produce calcium hypochlorite.
