What is "chlorofluoromethane"

n. (context organic compound English) Any halogenated derivative of methane containing both chlorine and fluorine; but especially CH₂ClF, sometimes used as a refrigerant

Chlorofluoromethane or Freon 31 is a gaseous mixed halomethane. It is a hydrochlorofluorocarbon (HCFC). It is used as a refrigerant and has an ozone depletion potential of 0.02.

Its crystal structure is monoclinic with space group P2 and lattice constants a = 6.7676, b = 4.1477, c = 5.0206 (.10 nm), β = 108.205°.

At an altitude of 22 km, traces of chlorofluoromethane occur (148 ppt).
