  • Chemical Classes:Toxic Gases & Vapors -> Acid Halides
  • Canonical SMILES:C(=O)(Cl)Cl
  • Inhalation Risk:A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
  • Effects of Short Term Exposure:Rapid evaporation of the liquid may cause frostbite. The substance is irritating to the eyes and respiratory tract. Inhalation of the gas may cause lung oedema and chemical pneumonitis. The effects may be delayed. Medical observation is indicated. Exposure at high levels could cause death.
  • Effects of Long Term Exposure:Lungs may be affected by repeated or prolongated exposure. This may result in impaired functions and decreased resistance to infection.
  • Uses Phosgene is used mainly as an intermediate in the manufacture of many types of compounds, including barbiturates; chloroformates and thiochloroforrnates; carbamoyl chlorides, acid chlorides, and acid anhydrides; carbamates; carbonates and pyrocarbonates; urethanes; ureas; azo-urea dyes, triphenylmethane dyes, and substituted benzophenones; isocyanates and isothiocyanates; carbazates and carbohydrazides; malonates; carbodimides; and oxazolidinedions. It is also used in bleaching sand for glass manufacture and as a chlorinating agent. Phosgene is an important commodity and a major industrial chemical used in the production of pesticides and plastics. As a chemical intermediate it is used in the manufacture of dyestuffs, isocyanates and their derivatives, and many other organic chemicals. It was formerly used as a war gas and is also known by itsmilitary designation as “CG.”Much of the clinical information on phosgene poisoning has been developed in the context of its military applications. It is also used in the pharmaceutical industries and in metallurgy. Of the total phosgene produced, 62% is used to manufacture toluene diisocyanate, and varying amounts are used to manufacture related chemicals. COCl2 is a very poisonous gas that was used in combat in the early twentieth century. When not concentrated, it smells like newly cut hay or grass. PHOSGENE is an intermediate in organic synthesis, especially production of toluene diisocyanate and polymethylene polyphenylisocyanate; in metallurgy to separate ores by chlorination of the oxides and volatilization; occurs as a product of combustion whenever a volatile chlorine compound comes in contact with a flame or very hot metal; originally manufactured as an agent for chemical warfare during World War I.
  • Physical Properties Colorless gas; density 4.34 g/L; heavier than air, density in air 3.41 (air=1); liquefies at 8.3°C; liquid density 1.432 g/mL; freezes at –118°C; slightly soluble in water with slow decomposition; also decomposed by alcohol and acids; soluble in benzene, toluene and acetic acid; critical temperature 182°C; critical pressure 56.04 atm; critical volume 190 cm3/mol.
  • Description Phosgene was prepared first in 1812 by reacting carbon monoxide with chlorine. Phosgene was used historically as a military gas in warfare. At present, it is used extensively to make polyurethanes. These urethane polymers produce polycarbonates and chloroformates for making pesticides and pharmaceuticals. Phosgene is a colourless, reactive, non-flammable gas that is heavier than air with a musty hay odour. Phosgene is commonly stored under high pressure as a liquid. Phosgene reacts with water to form corrosive acids, reacts with most metals in the presence of moisture, liberating hydrogen, an extremely flammable gas, and reacts violently with alkalis. As an industrial and commercially important chemical, phosgene is a precursor material/chemical intermediate, and has extensive application in the manufacture of a wide range of products such as polymers – polyurethanes and polycarbonates – pesticides, medicines, dyestuffs, some insecticides, pharmaceuticals, and in metallurgy.
