  • Electrochemical cogeneration of alkali metal halate and alkaline peroxide solutions
    Patent number: 5074975
    Abstract: This invention relates to a process and apparatus for the electrosynthesis of oxygenated halogen salts of alkali metals such as alkali metal halate, alkali metal hypohalite and alkali metal perhalate and an alkaline solution of hydrogen peroxide in the same electrochemical reactor. The invention also relates to a method for oxygen depolarization of cathodes in reactors that are used for the electrosynthesis of oxygenated halogen salts of alkali metals. The invention also relates to a method for the electrosynthesis of oxygenated chlorine salts of alkali metals which avoids the need to use chromates that are used in conventional chlorate production for the suppression of the cathodic reduction of hypochlorite.
