Noun
[edit]chlorofluorocarbon (plural chlorofluorocarbons) (abbreviation CFC or (rare) CFK)
- (organic chemistry) Any of a class of organic compounds in which the hydrogen atoms of a hydrocarbon are replaced with those of chlorine and fluorine; formerly used as refrigerants and aerosol can propellants but withdrawn due to causing damage to the ozone layer.
- 1989 March 7, Malcolm W. Browne, “In Protecting the Atmosphere, Choices Are Costly and Complex”, in The New York Times[1]:
- The proposed replacement for CFC-11, a chlorofluorocarbon used to make plastic foam and in central air-conditioning systems, is a compound called HCFC-22. This is a chlorofluorocarbon already in use in home air-conditioners, but it is more expensive than CFC-11 and its potential applications are limited by its inferior characteristics.
- 2009 February 12, Azadeh Ensha, “A Cellphone That Is Made With the Environment in Mind”, in The New York Times[2]:
- The Renew is also free of polyvinyl chloride, asbestos, chlorofluorocarbons and halons.
