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 ...
Halothane (2-bromo-2-chloro-1,1,1-trifluoroethane) is a dense, highly volatile, clear, colourless, nonflammable liquid with a chloroform-like sweet odour. It is very slightly soluble in water and miscible with various organic solvents.
