2-Chloro-1,1,1-trifluoroethane, also known as 1,1,1-trifluoro-2-chloroethane or Freon 133a, is an alkyl halide belonging to the category of hydrochlorofluorocarbons, having chemical formula F 3 C-CH 2-Cl. Under standard conditions, it appears as a colorless gas, partially soluble in water.
1,1,2-Trichloro-1,2,2-trifluoroethane, also called trichlorotrifluoroethane (often abbreviated as TCTFE) or CFC-113, is a chlorofluorocarbon. It has the formula Cl 2 FC−CClF 2 . This colorless, volatile liquid is a versatile solvent.
Between 2012 and 2017, concentrations of the gas jumped by 40 percent. [5] In 2020, the global mean concentration of CFC-113a was 1.02 parts per trillion with global emissions of 2.5 ± 0.4 ODP-Gg yr −1. [6]
For example, R-22 has one carbon atom, one hydrogen atom (2−1 = 1), two fluorine atoms, and one chlorine atom (4−2−1 = 1), so it is chlorodifluoromethane, while R-134 has two carbon atoms (2−1 = 1), two hydrogen atoms (3−1 = 2), four fluorine atoms, and no chlorine atoms (6−2−4 = 0), so it is one of the tetrafluoroethanes. This ...
Chlorotrifluoroethylene is produced commercially by the dechlorination of 1,1,2-trichloro-1,2,2-trifluoroethane with zinc: [3] CFCl 2-CF 2 Cl + Zn → CClF=CF 2 + ZnCl 2. In 2012, an estimated 1–10 million pounds were produced commercially in the United States. Addition of iodine monochloride to chlorotrifluoroethylene gives ...
1,2-Dichloro-1,1,2-trifluoroethane is a volatile liquid chlorofluoroalkane composed of carbon, hydrogen, chlorine and fluorine, and with structural formula CClF 2 CHClF. It is also known as a refrigerant with the designation R-123a .

1,1,2-Trifluoroethane or R-143, is a hydrofluorocarbon with formula CH 2 FCHF 2. It is a colourless gas at room temperature. It is an asymmetrical isomer of 1,1,1-trifluoroethane. 1,1,2-Trifluoroethane has a global warming potential of 397 for 100 years. [2] 1,1,2-Trifluoroethane can be obtained by the hydrogenation of 1,2 ...
