Abstract: A process for preparing sodium and aluminum chloride electrochemically is described in which, in an electrolytic cell containing aluminum as an anode and sodium as a cathode which are separated from one another by a sodium ion-conducting solid electrolyte, a fused electrolyte essentially containing sodium tetrachloroaluminate is electrolyzed in the anode compartment, aluminum chloride formed in this process is evaporated from the electrolytic cell and sodium is removed from the cathode compartment.

Abstract: Disclosed is a method for the simultaneous preparation of dicarboxylic acids and diamines from (a) polymers based on polyamides made by reacting dicarboxylic acids or derivatives thereof with diamines or (b) compounds containing essentially such polymers by decomposing these polymers into their constituent monomers by treating the polymers or compounds with a base and subsequently converting electrochemically the dicarboxylic-acid salts thus produced into the corresponding dicarboxylic acids and bases.

Abstract: An electrolysis cell for preparing alkali metals from a liquid alkali metal heavy metal alloy, including a tube arranged essentially horizontally having a closure device at each of the two ends of the tube. At least one solid electrolyte tube arranged concentrically in the tube and oriented with openings towards one end of the tube such that a first annular gap for conducting a liquid alkali metal, which forms an anode, is present between the inside of the tube and the outside of the solid electrolyte tube. An interior space in the solid electrolyte tube, sealed off from an alloy inlet, first annular gap and an alloy outlet, accommodates liquid alkali metal that can be used as a cathode.

Abstract: An electrolysis device producing alkali metals from a liquid alkali metal heavy metal alloy, including at least two connected tubes forming an electrolysis unit. Two solid electrolyte tubes are arranged concentrically in each tube and oriented with openings towards one end of each tube such that a first annular gap for guiding a liquid alkali metal forming an anode is located between the inside of the tube and the outside of the solid electrolyte tubes. An alloy inlet and outlet for the liquid alkali metal in each of the tubes leads into the first annular gap of a tube. An inner chamber sealed off from the alloy inlet, first annular gap, and alloy outlet in each solid electrolyte tube receives liquid alkali metal that can be used as a cathode connected to the alkali metal outlet. Two respective closure devices are arranged at the two ends of each tube.
