<p>METHOD OF ELECTROLYZING BRINE A practical method of electrolyzing sodium chloride brine on a commercial scale, obtaining in good yield a caustic product exceptionally low in salt content, is provided. The process necessarily involves working with a brine of lower calcium-ion content than is ordinarily used, using dimensionally stable anodes, using, preferably but not necessarily, a heat-treated ion-exchange membrane as a separator within the cell, and periodically taking action to reduce the cell voltage, by reducing the current or interrupting it, alone or with a concomitant flushing of the catholyte portion of the cell.</p> |
