Alias: Bis(trichloromethyl)carbonate;Triphosgene
Chemical name: Bis(trichloromethyl)carbonate
Molecular formula: C3Cl6O3
Molecular weight: 296.75
CAS No.: 32315-10-9
White crystal, with similar smell of phosgene; Solid Density 1.78 g/cm3, Melting Density1.629 g/cm3. Melting point79~83℃, Boiling point203 ~ 206℃/760 torr. Stability is strong,only a small amount of decomposition at the Boiling point, generating trichloromethyl chloroformate and phosgene. Insoluble in water, soluble in ether, THF, benzene, cyclohexane, chloroform, carbon tetrachloride, 1, 2-dichloroethane t. A molecular solid triphosgene can be decomposed into three molecular gas phosgene, and compared with gas phosgene ,, the use and transportation are safe and convenient to measurement, and can realize inverse drop and reaction, reaction close to equivalent etc. In industry, it is a general toxic material. In medicine, pesticide, organic chemical and polymer synthesis, it can replace phosgene or diphosgene in reaction.
the initial decomposition temperature of Solid phosgene 130℃,happen decomposition in damp atmosphere at 90℃; kept in dry, shady and cool place, away from fire, and organic amine.
