Abstract

25,957. Chemische Fabrik von Heyden Akt.-Ges. Nov. 18, 1912, [Convention date]. Void. [Published under Section 91 of the Act.] Alkali metals and alloys, obtaining.-A fused alkaline carbonate is electrolyzed with carbon anodes, which combine with the anions to form carbon dioxide. To allow lower temperatures to be used, other salts, such as chlorides, which are not decomposed, may be added to the carbonate. A mixture of 55 parts of sodium carbonate and 45 of sodium chloride melts at about 600‹ C.; the melting-point may be reduced by adding corresponding potassium salts. The alkali metal is produced in the form of vapour or liquid; a molten cathode of lead or other heavy metal may be employed. A current yield of 80 per cent may be obtained.
