| titleOfInvention | Improvements in the manufacture and production of solid urea or fertilizers containing urea |
| abstract | 332,948. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). April 29, 1929. Divided on 332,945. Manures.-Solid urea or products rich in urea are obtained in almost anhydrous form by adding to a pure solution of urea a quantity not exceeding 15 per cent of substances adapted to lower the solidification point of the anhydrous melt, preferably to 120‹ C. or less, evaporating until the water content of the mass is substantially less than 10 per cent, and spraying the melt or allowing it to run in a thin stream into liquids, for example, mineral oils or carbon tetrachloride, kept in motion. Suitable additions are substances which are soluble in water and in the anhydrous melts, do not decompose the urea, and preferably also possess a fertilizing action. Additions specified are diammonium phosphate, potassium phosphates, monocalcium phosphate, phosphoric acid, the nitrates of sodium, potassium, and ammonium, potassium chloride, ammonium sulphate, formamide, and acetamide. Examples are given. |
