摘要： A particular side frame design for use in an electromechanical cell with a catholyte flow pattern is disclosed wherein the cell is angled from the horizontal and the catholyte is fed into a gap in the cathode compartment between the liquid metal cathode and the membrane on the lower first end and exits the gap on the opposing higher second outlet end. The side frame is obliquely angled on the interior of the cell to prevent the escape of the flowable liquid metal cathode and to prevent contact of the acidic catholyte with the cell bottom.

摘要： A particular side frame design for use in an electrochemical cell with a catholyte flow pattern is disclosed wherein the cell can be generally horizontal or angled slightly from the horizontal and the catholyte is fed through a transition area into a gap in the catholyte compartment between the liquid metal cathode and the membrane on a first end and exits the gap on an opposing second outlet end. The side frame has opposing sides that are obliquely and downwardly angled in the corners to support the membrane in a wrinkle free manner so that the membrane is obliquely positioned between the liquid metal cathode and the anode. The membrane is above the level of the catholyte where the catholyte enters and exits the catholyte compartment, but drops to a level below the entry and exit points.

摘要： An aqueous solution of chloric acid and alkali metal chlorate is produced in an electrolytic cell having an anode compartment, a cathode compartment, and at least one ion exchange compartment between the anode compartment and the cathode compartment. The process comprises feeding an aqueous solution of an alkali metal chlorate to the ion exchange compartment, electrolyzing an anolyte in the anode compartment to generate hydrogen ions, passing the hydrogen ions from the anode compartment through a cation exchange membrane into the ion exchange compartment to displace alkali metal ions and produce an aqueous solution of chloric acid and alkali metal chlorate, passing alkali metal ions from the ion exchange compartment into the cathode compartment, removing the aqueous solution of chloric acid and alkali metal chlorate from the ion exchange compartment, and, increasing the concentration of chloric acid in the aqueous solution of chloric acid which is substantially free of anionic and cationic impurities to to provide a chloric acid concentration of 1.0 normal or greater.
