Cyanamide is mainly used for the production of cytidine hydrochloride, dye intermediate 3-amino-5-hydroxy-1,2,4-triazole, cyanuronamide, cyanamide, cyanamide, cyanamide, cyanurimide, thiourea, carbendazim, etc; It is also the raw material for the preparation of organic guanidine, and then produces barbituric acid, sulfonamide medicine, guanidine salt, etc; In medicine, it can also be used to produce fluorouracil, an anti-cancer drug; Cyanamide calcium salt is used in alcohol poisoning and has the effect of insect repellency. Cyanamide can be used as raw materials for chemical pesticides without residue, low toxicity and broad-spectrum, and also can be used to produce fungicides such as carbendazim, Benazolin, methylazoxyamine, azoxyamine, insecticide against aphimethacin, pyrimidinol, herbicides such as Chlorsulfuron, methasulfuron, methasulfuron, ether benzenesulfuron, benzyl Sulfuron, pyrazosulfuron and cyclozine. It is of great significance to the technical innovation of pesticide production, which can solve the environmental pollution problems that are difficult to solve when the general pesticide manufacturers buy lime nitrogen to produce pesticides, turn to buy cyanamide to produce pesticides, save equipment investment and reduce production cost. In addition, cyanamide can also be used to produce o-methyl-isourea, creatine, guanidine phosphate flame retardant, etc. at the same time, as a flame retardant with excellent performance, monocyanamide polyol or polyether solution can be used to produce polyurethane, which can obviously improve the flame retardant performance of polyurethane materials, and is a new fine chemical new material.
