摘要： An electrolytic cell employing a hydraulically impermeable membrane having a spacing means interposed between the anode and the membrane, is operated by providing a positive pressure differential between the cathode compartment and the anode compartment. The pressure differential is sufficient to maintain contact between the spacer and the membrane to provide uniform spacing between the anode and the membrane. In addition, this process provides sufficient spacing between the membrane and the cathode to provide efficient release of any gas formed and to prevent gas blinding at the cathode. Employing the positive pressure differential enables the cell to be operated at reduced energy costs when producing, for example, concentrated solutions of sodium hydroxide by careful control of the spacing between the membrane and the electrodes.

摘要： Current efficiency in an electrolytic membrane cell for the production of potassium hydroxide from aqueous solutions of KCl is considerably increased by maintaining the anolyte concentration of KCl at 250-350 grams per liter and the catholyte concentration of KOH at from about 410 to about 480 grams per liter. The electrolytic cell employs a cationic permselective membrane comprised of a hydrolyzed copolymer of a perfluoroolefin and a fluorosulfonated perfluorovinyl ether.

摘要： A process for the electrolysis of an aqueous solution of an alkali metal halide in an electrolytic cell having an anode compartment containing at least one anode, a cathode compartment containing at least one cathode, and a cation exchange membrane separating the anode compartment from the cathode compartment comprises feeding the aqueous solution of an alkali metal halide to the anode compartment; feeding an oxygen-containing gas to the cathode compartment; and electrolyzing the alkali metal halide solution to produce a halogen gas and alkali metal ions in the anode compartment. The alkali metal ions and water are passed through the cation exchange membrane into the cathode compartment to contact a hydrophilic porous cathode. The alkali metal ions, the water and the oxygen-containing gas produce a concentrated alkali metal hydroxide solution which flows through a hydrophilic porous cathode. The concentrated alkali metal hydroxide solution is removed from the cathode compartment to prevent a substantial accumulation of the concentrated alkali metal hydroxide solution in the cathode compartment.The process of the present invention provides operation of the membrane all independently of oxygen gas and liquid diffusion rates to permit high current densities to be employed.
