Dicyandiamide DCD

It is a white crystalline powder. Soluble in water, alcohol, ethylene glycol and dimethylformamide, almost insoluble in ether and benzene. Nonflammable. Stable when dry.

(1) As a raw material for guanidine salts and melamine. Various guanidine salts can be produced by reacting dicyandiamide with acid. Benzogyanamide obtained by the reaction of dicyandiamide and phenylnitrile is an intermediate for coatings, laminates, and molding powders.

(2) Used as a dye fixing agent. The dicyandiamide resin produced by the reaction of dicyandiamide and formaldehyde can be used as a dye fixing agent.

(3) Dicyandiamide fertilizer and dicyandiamide compound fertilizer can control the activity of nitrifying bacteria, adjust the conversion speed of nitrogen fertilizer in the soil, reduce nitrogen loss, and improve the efficiency of fertilizer use.

(4) As a fine chemical intermediate. It is used in medicine to prepare guanidine nitrate, sulfa drugs, etc.; it is also used to prepare thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive, etc.
The pharmaceutical intermediate 5-azacytosine can be obtained from the reaction of dicyandiamide and formic acid.

(5) Determination of cobalt, nickel, copper and palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, resin synthesis.
