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.
