Chlorofluorocarbons (CFCs): when derived from methane and ethane these compounds have the formulae CCl m F 4−m and C 2 Cl m F 6−m, where m is nonzero. Hydro-chlorofluorocarbons (HCFCs): when derived from methane and ethane these compounds have the formula CCl m F n H 4−m−n and C 2 Cl x F y H 6−x−y, where m, n, x, and y are nonzero.
CFC-113 is a very unreactive chlorofluorocarbon. It remains in the atmosphere about 90 years, [ 9 ] sufficiently long that it will cycle out of the troposphere and into the stratosphere . In the stratosphere, CFC-113 can be broken up by ultraviolet radiation (UV, sunlight in the 190-225 nm range), generating chlorine radicals (Cl•), which ...

1-Chloro-3,3,3-trifluoropropene (HFO-1233zd) is the unsaturated chlorofluorocarbon with the formula HClC=C(H)CF 3.The compound exists as E- (cis-) and Z- (trans-) isomers.The trans-isomer of this colorless gas is of interest as a more environmentally friendly (lower GWP; global warming potential) refrigerant in air conditioners. [1]
1-Chloro-1,1-difluoroethane (HCFC-142b) is a haloalkane with the chemical formula C H 3 C Cl F 2.It belongs to the hydrochlorofluorocarbon (HCFC) family of man-made compounds that contribute significantly to both ozone depletion and global warming when released into the environment.
Systematic name Common/trivial name(s) Code Use Chemical formula Tetrachloromethane Carbon tetrachloride, Freon 10 (Freon is a trade name for a group of chlorofluorocarbons used primarily as a refrigerant. The main chemical used under this trademark is dichlorodifluoromethane. The word Freon is a registered trademark belonging to DuPont.) CFC-10
1,2-Dichlorotetrafluoroethane, or R-114, also known as cryofluorane , is a chlorofluorocarbon (CFC) with the molecular formula ClF 2 CCF 2 Cl. Its primary use has been as a refrigerant. It is a non-flammable gas with a sweetish, chloroform-like odor with the critical point occurring at 145.6 °C and 3.26 MPa. When pressurized or cooled, it is a ...
