изоцианат

Name: HMDI; (1,6-Hexamethylene Diisocyanate); hexamethylene 1,6 - diisocyanate CAS NO.: 822-06-0 Name: MIC Methyl isocyanate; Isocyanatomethane; methyl isocyanate; methyl isocyanate ; CAS :624-83-9 Formula: C2-H3-NO Molecular Weight: 57.06 Relative density: 0.9599 (20/20 °C) Boiling point: 39.1 °C Flash point: <-15 °C (closed cup). Ignition point: 534 °C steam Density: 1.42 Vapor Pressure: 46.39kPa (348mmHg20 °C) 15 °C when the water solubility: 1%; 20 °C 6.7% when the colorless clear liquid, a strong irritant. In addition to stainless steel, nickel, glass, ceramics, all other materials have been in contact with the corrosion risk. In particular, can not use iron, steel, zinc, tin, copper or its alloy as the packing containers. Easily and contain active hydrogen atoms of compounds: amines, water, alcohols, acids, alkalis react. Methylamine reacts with water, carbon dioxide; in the presence of excess water, methylamine and then reacted with the MIC of 1,3 - dimethyl urea, is formed when the MIC in excess of 1,3,5 - trimethyl biuret. These two reactions are exothermic. A catalyst in the presence of pure material conditions, the occurrence of homopolymerization reaction and release heat. Case of heat, open flame, oxidizers flammable. Combustion of MIC vapor, nitrogen oxides, carbon monoxide and hydrogen cyanide. High temperature (350 540 °C) can form hydrogen cyanide under the pyrolysis. Case of thermal decomposition of nitrogen oxide gas release.
