Dicyandiamide CAS 461-58-5

What is Dicyandiamide？

Dicyandiamide, abbreviated as DICY or DACD, is a dimer of cyanamide and a cyano derivative of guanidine. It is a white crystalline powder. It is soluble in water, alcohol, ethylene glycol and dimethylformamide, and almost insoluble in ether and benzene. It is non-flammable. It is stable when dry. Dicyandiamide curing agent belongs to the earliest type of heat-curing latent curing agent used. It is solid at room temperature and insoluble in epoxy resin. It is dispersed in epoxy resin in the form of microparticles and then heated to react. Once heated to near the melting point, it begins to dissolve and react rapidly to cure.

응용 프로그램

(1) Dicyandiamide is used as a raw material for guanidine salts and cyanamide. Various guanidine salts can be produced by reacting dicyandiamide with acid. Benzene cyanamide obtained by the reaction of dicyandiamide and benzonitrile is an intermediate for coatings, laminates, and molding powders.
(2) Dicyandiamide is used as a dye fixative. The dicyandiamide resin obtained by the reaction of dicyandiamide and formaldehyde can be used as a dye fixative.
(3) Dicyandiamide fertilizers and dicyandiamide compound fertilizers can control the activity of nitrifying bacteria, regulate the conversion rate of nitrogen fertilizer in the soil, reduce nitrogen loss, and improve the efficiency of fertilizer use.
(4) Dicyandiamide is used as a fine chemical intermediate. In medicine, it is used to prepare guanidine nitrate, sulfonamide 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 by reacting dicyandiamide with formic acid.
(5) Dicyandiamide for the determination of cobalt, nickel, copper and palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, resin synthesis.
