Abstract

18,207. Lidh�lm, J. H. Sept. 12, 1910, [Convention date]. Ammonia; cyanamide; dicyandiamide.-Ammonia is obtained by heating calcium cyanamide or nitrogen compounds prepared from it, such as cyanamide or dicyandiamide, with water and an alkali hydrate or carbonate. The calcium cyanamide may be heated with the alkali solution, or may be treated with carbonic acid and then lixiviated, or may be lixiviated and the solution treated with carbonic acid to obtain, for instance, cyanamide or dicyandiamide, which is continuously fed to the boiler in which the ammonia is produced, the carbonic acid produced by the reaction being used to treat the calcium cyanamide.
