Abstract
117,823. Haworth, F. W., (Elektrisk Norsk Hydro Kvoelstofaktieselskab). April 10, 1917. Manures. - Ammonium nitrate is obtained in dry granular form suitable for agricultural purposes by drying a moist mixture of ammonium nitrate with bog iron ore or kieselguhr at a temperature not above 130‹ C. with agitation. A small quantity of plaster of paris (gypsum) may be added to the ammonium nitrate before treatment, and the suspension of bog iron ore which is preferably employed may be made more viscous by adding gelatinized starch, kieselguhr, potassium salts, or ammonium salts. The drying may be effected in two stages, first at a comparatively low temperature such as 20-40‹ C., and then at a higher temperature such as 100‹ C.
