Application:

(1) As a raw material for guanidine salt and melamine diamines. Various guanidine salts can be produced by reacting dicyandiamide with acid. The reaction of dicyandiamide and phenylnitrile to phenylmelamine diamine is an intermediate in coatings, laminates and molding powders.

(2) Used as dye fixing agent, dicyandiamide resin prepared by reaction of dicyandiamide and formaldehyde can be used as dye fixing agent.

(3) dicyandiamide fertilizer, dicyandiamide complex fertilizer can control the activities of nitrifying bacteria, so that the conversion rate of nitrogen fertilizer in the soil can be adjusted, reduce nitrogen loss, and improve the efficiency of fertilizer use.

(4) As a fine chemical intermediate. In medicine, it is used to prepare guanidine nitrate, sulfonamides, etc.; It is also used to produce thiourea, cellulose nitrate stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive and so on. The pharmaceutical intermediate 5-azacytosine can be obtained by the reaction of dicyandiamide with formic acid.

(5) Verification of cobalt, nickel, copper and palladium, organic synthesis, nitrocellulostabilizer, hardener, descaling agent, vulcanization accelerator, resin synthesis.
