Sigma KEE - Chlorofluorocarbon

appearance as argument number 1

(documentation Chlorofluorocarbon EnglishLanguage "A chlorofluorocarbon (CFC) is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane. A common subclass are the hydrochlorofluorocarbons (HCFCs), which contain hydrogen, as well. They are also commonly known by the DuPont trade name Freon. The most common representative is dichlorodifluoromethane (R-12 or Freon-12). Many CFCs have been widely used as refrigerants, propellants (in aerosol applications), and solvents. The manufacture of such compounds has been phased out by the Montreal Protocol because they contribute to ozone depletion. [from Wikipedia]") Cars.kif 1790-1797
