Abstract

1,207,239. Sodium carbonate and bicarbonate. CHEMISCHE FABRIK KALK G.m.b.H. 25 July, 1968 [29 Aug., 1967], No. 35605/68. Heading C1A. Sodium bicarbonate is produced by adding to a mother liquor which remains from a sodium hydroxide solution obtained from alkali chloride electrolysis, after reacting with CO 2 and removing NaHCO 3 precipitated, (a) ammoniabearing vapours resulting from the ammonia regeneration step of the ammonia-soda process, and (b) solid rock salt, until saturation with ammonia and rock salt is achieved, so that the solution contains about 145 g. of Na 2 O per litre, and carbonating with CO 2 to precipitate sodium bicarbonate. The sodium bicarbonate may be calcined to give sodium carbonate.
