摘要： Alkali metal chlorides, e.g. brine, are electrolized in the presence of substantially horizontal anodes provided on the underside with channel- or groove-like recesses. The anodes and/or the course of the channel- or groove-like recesses in the anodes are positioned to define spaced apart regions between the anodes so as to provide for an outflow of chlorine from the space between the electrodes and for an inflow of brine into this space.

摘要： In electrolytic apparatus comprising cell chambers through which is passed an electrolyte and in which sets of anode plates are provided, each of which are connected to current-feeding center pins, and the mutually staggered electrode plates protrude into the gaps between plates having the opposite polarity. To ensure a simple, quick and reliable installation and removal of the anode plates, the center pin is provided with contact straps, which are spaced apart in the longitudinal direction of the pin and serve to secure the anode plate. The contact straps are suitably spaced about 180.degree. apart and have at least one opening, which consists preferably of a tapped bore.The electrolytic apparatus is used in processes of producing alkali chlorate by the electrolytic decomposition of aqueous alkali chloride solutions.

摘要： An electrolytic cell comprising bipolar electrodes is employed for electrochemical deposition of copper, zinc, lead, nickel or cobalt. An interior space is provided between the cathode side and the anode side of a bipolar electrode. The electrolyte can flow substantially without an obstruction through the interelectrode space between adjacent electrodes. The current densities in the interelectrode space amount to 800 to 8000 A/m.sup.2. Gas is evolved on the anode side of the bipolar electrodes and causes liquid to flow along the anode side. In the middle of the height of the anode side that liquid flow has a vertical component having a velocity of 5 to 100 cm/second. Electrolyte solution flows from the upper edge portion of the anode side to a return flow space, in which the solution flows downwardly. From the return flow space the solution is returned to the lower portion of the interelectrode space.

摘要： The ammonium polysulfide is produced in at least one electrochemical cell, to which an aqueous ammonium sulfide solution is supplied as electrolyte. The cell comprises an anode, a gas diffusion cathode, and between the anode and the cathode an electrolyte chamber, where the cell voltage is 0.01 to 5V. The cathode has an electrically conductive, gas-permeable carbon layer, over which flows gas containing free oxygen, and which is in contact with the electrolyte. O.sub.2 -containing gas is introduced into the electrolyte chamber, thereby forming hydroperoxide anions (OOH.sup.-) in the electrolyte chamber. From the electrolyte chamber a solution containing ammonium polysulfide and a residual gas are withdrawn.

摘要： Alkali hydroxide, chlorine and hydrogen are produced from an aqueous alkali chloride solution by membrane electrolysis. A high-NaCl solid salt, which contains impurities, is dissolved in water in a salt dissolver. Precipitating chemicals are added to the salt solution to precipitate the impurities. The resulting mixture is fed to a thickener, from which precipitates and clarified raw brine are separately withdrawn. The clarified raw brine from the thickener is divided at a ratio between 2:1 and 20:1 into first and second partial streams. The larger first partial stream is mixed with the salt solution and the precipitating chemicals before entering the thickener and the resulting mixture is fed to the thickener. The second partial stream of the clarified raw brine is fed through a fine purifier to the electrolytic cell. Spent brine from the electrolytic cell is fed to the salt dissolver.
