果博东方 www.cqrdzs.com Melamine is an industrial chemical; a white crystalline powder consisting of nitrogen, carbon and hydrogen.
Most melamine is used as a starting product for the manufacture of adhesives and resins that are used in woodbased panels, laminate floors and decorative surfaces for furniture. It is also present in thermoset plastics, flame retardants and many other products.
Molecular formula: C3N6H6. C3N3 (NH2)3 Weight : 126.12
CAS No.: 108-78-1 EINECS No：203-615-4
Physical capability: White crystal powder, innoxious, flavorless.
Relative density: 1570kg/m3
Melting point: It be melt under 354℃ under ordinary pressure.
Sublimation temperature: 300℃
Dissolvability: It can dissolve in carbinol, formaldehyde, acetic acid, hot glycol, glycerin, pyridine; it lightly dissolve in water, ethanol; it cannot dissolve aether, benzene, and carbon tetrachloride. Its water solution presents alkalescence.
Chemical Capability: Melamine presents alkalescence, can react with various acidums to generate melamine salt. In strong acid or strong alkali liquor, melamine will hydrolyze---amidocyanogen will be slowly replaced by hydroxyl, thus generate cyanuric acid diacid amide, cyanuric acid monamide, and cyanuric acid. Among them, the reaction of melamine and formalin is the most important part.
