Меламин

Chinese alias: Dense amine, protein concentrate, 2, 4, 6- three amino - 1,3,5- triazines, 1,3,5- triazine - 2,4,6- three amines, 2,4,6- three semicarbazides, melamine, cyanogen urea triacid amides. Chinese abbreviation: Three amines English name: Melamine, 1,3,5-Triazine-2,4,6-triamine; 2,4,6-Triamino-1,3,5-triazine; 2,4,6-Triamino-s-triazine; Aero; Cyanuramide; Cyanuric triamide; Cyanurotriamide; IUPAC naming: 1,3,5- triazine - 2,4,6- three aminos Chemical Formula: C3H6N6 Molecular weight: 126.15 CAS No.: 108-78-1 EINECS No.: 203-615-4Density: 1.573g/cm3 (16 degrees) Melting point: 354 degrees Content: ≥ 99.8% Physicochemical properties: The melamine traits is the pure white monocline prismatic crystal, is not inflammable, tasteless, low poisonous. Sharply heating the decomposition, rapid heating sublimation, sublimation temperature 300 degrees.Slightly soluble in water (3.1g / L at room temperature), Namely slightly soluble in cold water, soluble in hot water.May dissolve in the methyl alcohol, the formaldehyde, the ethanoic acid, the hot glycol, the glycerine, the pyridine and so on, extremely slightly soluble in hot ethyl alcohol.Insoluble in benzene, carbon tetrachloride, acetone, ethers.The melamine mainly uses in the industrial chemicals, is harmful to the body, cannot use in the food processing or food additives.And hydrochloric acid, sulfuric acid, nitric acid, acetic acid, oxalic acid, etc. can form melamine salt.Melamine is a trimer Cyanamide, from it made-up of resin, thermal decomposition will release a lot of nitrogen, so it can be used as fire retardant. Uses: Melamine is a versatile basic organic chemical intermediate products, the main use is as the production of melamine formaldehyde resin (MF) of raw materials.Melamine can be do fire retardants, water-reducing agent, formaldehyde detergents etc.This resin hardness ratio urea resin is high, is not flammable, water resistant, heat-resisting, bears the aging, to bear the electric arc, to bear the chemical etching, to have the good insulating ability, glossiness and the mechanical strength,Widely used in wood, plastic, paint, paper, textile, leather, electrical, pharmaceutical and other industries.
