A chlorofluorocarbon (CFC) is an organic compound made up of carbon, chlorine, and fluorine, produced like a volatile derivative of methane and ethane. A common subclass are the hydrochlorofluorocarbons (HCFCs), that have hydrogen, too. They are also frequently known by the DuPont control name Freon. The most common consultant is dichlorodifluoromethane (R-12 or Freon-12). Various CFCs have been completely widely used as refrigerants, propellants (in suspension applications), and solvents. The manufacture of suchcompounds has become phased out by the Montreal Protocol because that they contribute to ozone depletion.
Applications take advantage of the low degree of toxicity, low reactivity, and low flammability with the CFCs and HCFCs. Every permutation of fluorine, chlorine, and hydrogen based on methane and ethane has been evaluated and most have been commercialized. Furthermore, many examples are known for higher numbers of carbon as well as related compounds that contain bromine. Uses include refrigerants, blowing agents, propellants in medicinal applications, and degreasing solvents. Environmental impacts
As previously talked about, CFCs were phased out with the Montreal Process due to their component in ozone depletion. Nevertheless , the atmospheric impacts of CFCs are not limited to it is role because an active ozone reducer. This kind of anthropogenic chemical substance is also a greenhouse gas, with a greater potential to boost the greenhouse impact than LASER.
Infrared groups trap heat from getting away earth's ambiance. In the case of CFCs, the most effective of these bands are located on the spectral area вЂ“ called an atmospheric window due to the relative openness of the atmosphere within this area.
The effectiveness of CFC rings and the unique susceptibility of the atmosphere, at which the compound absorbs and emits radiation, are two factors that...
