Important Pesticide Intermediates Hydrogen Cyanamide industrial raw materials, medicine and agricultural fertilizer
Excellent flame retardant materials
Crystalline cyanamide is mainly used to produce O-methyl isourea, creatine, guanidine phosphate flame retardants and so on. At the same time, as a good flame retardant material, monocyanamide polyol or polyether solution is used to produce polyurethane, which can obviously improve the flame retardancy of polyurethane material. It is a new fine chemical new material.
Fixing agent material
Dicyanamide can be used to produce fixing agent Y, fixing agent G, fixing agent M and fixing agent B. For example, cyanamide, polyformaldehyde and copper aldehyde are used as fixing agent B, which is a kind of gray-yellow powder for the post-treatment of direct dyes and dyeing. For example, 30.9 phr Diethyltriamine and 24.8 phr dicyandiamide were reacted at 100 C and then heated at 155 C for 5 h, then cooled and crushed to a colorless powder. It is a formaldehyde free fixing agent, and has low cost and green future.
1. It is irritating and corrosive to the skin and can cause severe dermatitis. Inhalation or inhalation can cause mucosal irritation, transient flushing, headache, dizziness, shortness of breath, tachycardia and hypertension.
2. Mutagenicity test: slight irritation to rabbit skin and severe irritation to eyes. The original drug belongs to weak allergic drug to guinea pig skin allergy test.
3, the maximal non dose 0.2mg/kg/d of 90d subchronic feeding test in rats. Both cyanamide and 50% aqueous solution are medium toxic. Safe operation should be paid attention to when using them.
Cyanamide is a transparent liquid, which is soluble in alcohols, phenols, amines and ethers at M.P. - 115 C and B.P. - 8.5 C. It is soluble in benzene and halogenated hydrocarbons, and 77.5% in water at 15 C. High concentration of cyanamide is unstable and easy to polymerize, often adding stabilizer. The general commodity is 50% cyanamide solution, n20D 1.4050, relative density 1.082.
Cyanamide is an important intermediate of pesticides. It can be used to prepare fungicides such as carbendazim, phenylsulfuron, methyl pyrimethylamine and pyrimethylamine, insecticides such as azithromycin, pyrimidine oxyphosphate, herbicides such as chlorosulfuron-methyl, methsulfuron-methyl, methyl sulfuron-methyl, ethephensulfuron-methyl, bensulfuron-methyl, pyrimidine-methyl, cyclazine, etc.
Used in the pharmaceutical industry as a raw material for the production of cytarabine hydrochloride, in the dye industry for the production of intermediate 3-amino-5-hydroxy-1,2,4-triazole. In addition, it is also used as raw material for organic synthesis and plastics, producing cyanuramide, dicyandiamide, methyl cyanocarbamate, etc.
Uses Liquid Monocyanamide Used in Industrial Raw Materials, Pharmaceutical, Pesticide Intermediates, Agricultural Fertilizers, Plant Regulators, Food Additives, etc.
