Dicyandiamide(461-58-5)

Uses: The main uses of dicyandiamide include: (1) as raw material of guanidine salt and melamine. Various guanidine salts can be produced by reaction of dicyandiamide with acid. Phenyltrimethylenediamine obtained by the reaction of dicyandiamide and phenylnitrile is the intermediate of coating, laminate and molding powder. (2) As a dye fixing agent, dicyandiamide resin prepared by 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, regulate the conversion rate of nitrogen fertilizer in the soil, reduce the loss of nitrogen, and improve the use efficiency of fertilizer. (4) As a fine chemical intermediate. In medicine, it is used to prepare guanidine nitrate, sulfonamide drugs, etc; It is also used to produce thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive, etc. The pharmaceutical intermediate 5-azacytosine can be obtained by the reaction of dicyandiamide and formic acid.
