Abstract
Relates to a process for the manufacture of anhydrous alkaline-earth chlorides by adding ammonium chloride and the oxide, hydrate, carbonate, or oxychloride of the alkaline earth metal to a melt of one or more haloid salts of a metal electropositive to the alkaline earth metals, such as a mixture of sodium and potassium chlorides, and collecting the ammonia or ammonium carbonate evolved. The ammonium chloride may be 10 to 20 per cent in excess of the theoretical quantity. The ammonia or ammonium carbonate is converted into ammonium chloride for re-use by combining it with hydrochloric acid obtained by passing a mixture of chlorine and steam over carbon heated to 300 DEG C.ALSO:Calcium, magnesium, and other alkaline earth metal chlorides in anhydrous condition suitable for electrolysis are obtained by adding ammonium chloride and the oxide, hydrate, carbonate, or oxychloride of the alkaline earth metal to a melt of one or more haloid salts of a metal electro-positive to the alkaline earth metals, such as a mixture of sodium and potassium chlorides, and collecting the ammonia or ammonium carbonate evolved. The ammonium chloride may be 10 to 20 per cent in excess of the theoretical quantity. The ammonia or ammonium carbonate is converted into ammonium chloride for re-use by combining it with hydrochloric acid obtained by passing a mixture of chlorine and steam over carbon heated to 300 DEG C.
