Chlorofluoromethane or Freon 31 is the hydrochlorofluorocarbon (HCFC) with the formula CH2ClF. It is a colorless, odorless, flammable gas. [1] It is a class II ozone depleting substance and in accordance with the montreal protocol, its production and import were banned on 1 January 2015. [2]
Pyrolysis of a mixture of dichlorofluoromethane and chlorofluoromethane gives hexafluorobenzene: [1]
It was used as a refrigerant and has an ozone depletion potential of 0.02.
Its crystal structure is monoclinic with space group P21 and lattice constants a = 6.7676, b = 4.1477, c = 5.0206 (0.10−1 nm), β = 108.205°. [3]
At an altitude of 22 km, traces of chlorofluoromethane occur (148 ppt). [4]
