Product Name:Diphosgene
English Name:Diphosgene
CAS No.:503-38-8
Aliases:Diphosgene, Trichloromethyl chloroformate
Molecular Formula:C2Cl4O2
Physical Properties:Colorless liquid with pungent odor. Melting point -57°C, boiling point 128°C, relative density (water=1) 1.63. Insoluble in water, miscible with ethanol, diethyl ether, benzene and most organic solvents. Highly reactive; undergoes hydrolysis, alcoholysis and ammonolysis. In moist air it gradually hydrolyzes to form chloroformic acid and hydrogen chloride; toxic. Thermal decomposition releases highly toxic phosgene.
Uses:Mainly used as a phosgene substitute for introducing carbonyl chloride groups in organic synthesis, preparing acyl chlorides, isocyanates, carbonates, and intermediates for pesticides and pharmaceuticals. Also used in chemical warfare agent research and as an organic synthesis raw material.
