Abstract: Proposed is an electrolytic method for the production of sodium and aluminiu m chloride in an electrolytic cell with an aluminium anode and a sodium cathode separated from each other by a sodium-ion- conducting solid electrolyte. In the anode region, molten electrolyte containing essentially sodium tetrachloroaluminate is electrolysed, the aluminium chloride produced being evaporated out of the cell and the sodium produced being tapped off from the cathode region.

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: Regenerating plastic diaphragms comprises mixing a soln. of mineral acid (I) with a corrosion inhibitor (II) and passing the mixt. through the diaphragm for 0.1-84 (pref. 1-72, esp. pref. 2-24) hrs. at 0-100 (pref. 40-80, esp. pref. 50-70) degrees C. Also claimed are plastic diaphragms obtd. by this process. (I) consists at least partly, pref. entirely, of HCl in a concn. of 0.3-20 (pref. 2-10) wt%, pref. contg. NaCl in a concn. up to the satn. pt., pref. up to 250 g/l. Pref. soln. (I) also contains 500-5000 ppm Cu and/or Fe cpds., esp. Cu(II) and/or Fe(III) salts. The mixt. contains 0.005-5 (pref. 0.05-0.5) wt% (II). Component (II) contains alkynol(s), esp. an alkyne-diol, pref. mixed with 1-25 wt% amine, esp. hexamethylenetetramine (HMTA), ethylhexylamine or diethylhexylamine, and/or 0.1-3 wt% surfactant, esp. a quat. ammonium salt.
