摘要： Electrolysis of alkali metal chloride solutions to produce chlorine and alkali metal hydroxides is accomplished in a cell comprising an anode compartment, a cathode compartment, a cation permeable divider separating the anode compartment from the cathode compartment, where the anode compartment contains an anode separator. The anode separator is comprised of a porous plate of a valve metal having an electrochemically active coating on the face, and an electrochemically non-active barrier layer on the back and a portion of the interior. The anode separator is positioned in the anode compartment so that the back of the anode separator is spaced apart from the cation permeable divider. An alkaline brine zone is formed between the anode separator and the cation permeable divider which increases the service life of the cation permeable divider. In addition, the anode separator provides improved chlorine gas separation properties, increased service life for the electroconductive coating on the face, and enables the cell to operate with a reduced cell voltage.

摘要： An electrolytic cell suitable for use in electrolyzing ionizable chemical compounds, particularly alkali metal halide brines and hydrohalic acids, which comprises a cell body having an anode compartment containing a porous anode and a cathode compartment containing a cathode said compartments being separated from each other by a prestretched, taut membrane barrier which is substantially impervious to gases and liquids and which is selected from a hydrolyzed copolymer of a perfluorinated hydrocarbon and a sulfonated perfluorinated hydrocarbon and a sulfonated perfluorovinyl ether, and a sulfostyrenated perfluorinated ethylene propylene polymer, said barrier being pretreated by hydrolyzing and stretching prior to insertion in the cell.Such cells can be operated at constant low voltage, and are not subject to erratic operating voltages which are due, in part at least, to the accumulation of gases between the anode and diaphragm.

摘要： In an electrolytic treatment of alkali halide for the manufacture of alkali hydroxide, a three-chamber type reaction vessel assembly is used so as to provide an anodic chamber, an intermediate chamber and a cathodic chamber arranged in succession one after another and mutually separated by means of anodic (i.e., cationic selective) ion exchange membranes. From the intermediate chamber, low concentration caustic alkali solution is obtained, while from the cathodic chamber, high concentration caustic alkali solution is obtained. In this electrolytic process, the system is operated with the cathodic chamber supplied with no water or aqueous content. The high concentration caustic alkali solution is made from water and alkali metal ions conveyed from the intermediate chamber to the cathodic chamber and exclusively and osmotically passed through the anodic ion exchange membrane. The polymers or copolymers of the anodic ion exhange membrane include sulfonic acid, carboxylic acid and/or phenolic radicals. As the method for the introduction of these radicals, formation of corresponding copolymers may be utilized in the most recommended way. As an example, the membrane may comprise a fluorinated polymer having a cyclic ring structure unit and pendant type sulfonic acid radicals.

摘要： A cellular metal structure comprising a continuous interconnected network of electrolytically deposited metal defining a plurality of substantially convex cellular compartments therebetween is disclosed. The metal structure is produced by positioning a cellular array of substantially convex and substantially electrically nonconductive particles having a plurality of interstitial spaces therebetween between the anode and cathode of an electrolytic cell. The array is at least partially immersed in an aqueous solution of an electrolyte suitable for the electrolytic deposition of the metal. A direct current potential is applied between the anode and cathode to electrolytically deposit a continuous interconnected network of metal in the interstitial spaces defined between the cellular array of substantially convex particles.
