Laboratory tests were conducted to determine the feasibility of incorporating the nitrogen loss inhibitors dicyandiamide (DCD), thiourea (TU), phenyl phosphorodiamidate (PPDA), and potassium ethyl xanthate (PEX) into granular urea. Tests were made to determine the stabilities, solubilities, and dissolution rates of the inhibitors in urea melts and urea solutions; to determine the effect of inhibitor addition on the rate of weight loss and qualitative composition of volatiles evolving from urea melts; to determine the melting point diagrams for the urea inhibitor systems; and to determine the heat of fusion for the urea-inhibitor mixtures.
