Abstract

816. Gelhaar, S. J. Jan. 12. Urea salts.-Salts of urea are produced by treating calcium or other cyanamide with an acid of such nature and concentration and at such a temperature, that the formation of impurities of the nature of dicyandiamidine &c. is prevented, the duration of the operation depending upon the acid and temperature. Sulphuric, perchloric, hydrochloric, nitric, and formic acids may be used, but turkey-red oil has no action.
