Chemical properties

Using and storage as specified can not be decomposed and avoid touching with oxide.The solubility in absolute ethanol at 13 °C is 1.26% and in water is 2.26%.Easily soluble in hot water, the aqueous solution will slowly decompose to produce ammonia gas when the temperature is above 80 °C.When the crystal of dicyandiamide is heated to the melting point, it will heat up violently immediately after melting to generate melamine, melamine, etc.
