Chlorofluoromethane Chemical Properties,Uses,Production
Description
Chlorofluoromethane or Freon 31 is the hydrochlorofluorocarbon (HCFC) with the formula CH2ClF. It is a colorless, odorless, flammable gas.
Chlorofluoromethane is a gaseous mixed halomethane. Its crystal structure is monoclinic with space group P21 and lattice constants a = 6.7676, b = 4.1477, c = 5.0206, β = 108.205°. In altitude of 22 km traces of chlorofluoromethane occur It is used as a refrigerant with ozone depletion potential 0.02.
Uses
Pyrolysis of a mixture of dichlorofluoromethane and chlorofluoromethane gives hexafluorobenzene:
3 CHCl2F + 3 CH2ClF → C6F6+ 9 HCl
It was used as a refrigerant and has an ozone depletion potential of 0.02.
Safety Profile
Confirmed carcinogen with experimental carcinogenic data. Moderately toxic by inhalation. Mutation data reported. When heated to decomposition it emits very toxic fumes of Cland F-. See also CHLORINATED HYDROCARBONS, ALIPHATIC; and FLUORIDES.
