CFC, Dichlorofluromethane, CF2Cl2 ( CFC-12 ), Trichlorofluromethane, CFCl 3 ( CFC-11)
Chlorofluorocarbons (CFCs), the hydrocarbons containing both chlorine and fluorine (CFCs), are used as refrigerants, blowing agents, cleaning fluids, solvents, and as fire extinguishing agents. They have been shown to cause stratospheric ozone depletion and have been banned for many uses.
CFCs are very stable chemical compounds. In the stratosphere, CFCs are photolyzed (by incoming solar UV) to form carbon dioxide, CO2, hydrogen fluoride, HF, and ultimately chlorine radicals. These chlorine species are crucial in the destruction of the ozone layer over Antarctica and elsewhere.
