Dicyandiamide is White crystalline powder. The water solubility of dicyandiamide is 2.26% at 13degrees centigrade. When the aqueous solution at 80degrees centigrade, Dicyandiamide will gradually decomposed to ammonia. The Ethanol, ether solubility of dicyandiamide is respectively 1.26% and 0.01% at 13degrees centigrade. Dicyandiamide is soluble in liquid ammonia, hot water, ethanol, acetone hydrate, dimethyl formamide, and insoluble in ether, do not dissolve in benzene and chloroform. Relative density ( d254 ) 1.40 . Melting point 209-212degrees centigrade. Stable in dry air, incombustible, low toxicity, the median lethal dose (mice by mouth ) > 4000mg/kg. The maximum allowable concentration of dicyandiamide is 5 mg / m?in the air .Dicyandiamide is a synthetic medicine, pesticide and dye intermediates. Dicyandiamide Can be produced guanidine nitrate, printing and dyeing fixing agent, decolorizing flocculant, adhesives, fertilizer nitrogen inhibitor.
