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 P21 and lattice constants a = 6.7676, b = 4.1477, c = 5.0206 (.10−1 nm), β = 108.205°.[1]
At an altitude of 22 km, traces of chlorofluoromethane occur (148 ppt).[2]
