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.
Definition
ChEBI: Chlorofluoromethane is a hydrochlorofluorocarbon.
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.
