Abstract
A process for producing a concentrated aqueous solution of an alkali metal chlorate and an alkali metal chloride comprises feeding an aqueous alkali metal chloride solution to a first electrolysis zone at an initial feed rate. The aqueous alkali metal chloride is electrolyzed to produce a concentrated chlorate solution comprised of an alkali metal chlorate and the alkali metal chloride. A portion of the concentrated solution is fed to an analysis zone and analyzed to measure the ratio of the concentration of the chlorate ion to the concentration of the chloride ion. The measured ratio is compared in a processing zone with a predetermined value range for the ratio and, where the measured ratio falls outside of the predetermined value range, altering the initial feed rate of alkali metal chloride to the first electrolysis zone. The concentrated alkali metal is removed from the first electrolysis zone to a product solution collection zone. The novel process of the present invention permits the continuous operation of the electrolytic cells by frequently and rapidly determining the chlorate and chloride concentrations by reverse phase liquid chromatography employing an ion pairing eluent solution. The process permits adjustments to the various feed streams to maintain the required ion concentrations without the long delays required by other processes while reducing the requirements for manual operators.
