Abstract
298,196. Stockholms Superfosfat Fabriks Aktiebolag. Oct, 5, 1927, [Convention date]. Manures.-A mixed fertilizer containing ammonium nitrate and ammonium phosphate, with or without ammonium sulphate, is made by passing gaseous ammonia through a mixture of nitric and phosphoric acids, to which sulphuric acid may be added, at a temperature not much exceeding 100‹ Centigrade, the acids being so concentrated that solid salts are precipitated. Similarly, ammonia may be passed into a solution of ammonium phosphate in nitric acid or of ammonium nitrate in phosphoric acid, sulphuric acid or ammonium sulphate being present if desired. Specification 292,068 is referred to.
