Abstract

333,353. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 1, 1929 Manures.-Calcium cyanamide is rendered free from dust and non-caustic by mixing it with a solid ammonium salt such as ammonium nitrate or with solid phosphoric acid. The ammonia liberated from the ammonium salt may be removed by heating the mixture to a temperature not above 150‹ C. and when using ammonium nitrate a granular product is obtained. The cyanamide may be partly neutralized by treatment with solid phosphoric acid, and then further treated with ammonium nitrate. Industrial products containing ammonium salts such as commercial calcium nitrate which contains ammonium nitrate may be used.
