Freon
Freon
Freon (/ˈfriː.ɒn/) is a registered trademark of The Chemours Company, which uses it for a number of halocarbon products. They are stable, nonflammable, moderately toxic gases or liquids which have generally been used as refrigerants and aerosol propellants. These are types of chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), and hydrofluorocarbon (HFC) compounds.
Etymology
The term "Freon" is a brand name owned by The Chemours Company, and it is derived from the terms "freezing" and "eon", a suffix referring to a substance. It was first introduced in the 1930s by the company's predecessor, DuPont.
Usage
Freon and other CFCs have been widely used in air conditioning and refrigeration systems because they are nonflammable, noncorrosive, nonpoisonous, and easy to manufacture. However, they have been linked to ozone depletion and are being phased out in favor of other types of refrigerants.
Related Terms
- Chlorofluorocarbon (CFC): A type of compound that contains carbon, chlorine, and fluorine. They are stable and nonflammable, but they have been linked to ozone depletion.
- Hydrochlorofluorocarbon (HCFC): A type of compound that contains hydrogen, carbon, chlorine, and fluorine. They are less stable and therefore less likely to reach the ozone layer than CFCs.
- Hydrofluorocarbon (HFC): A type of compound that contains hydrogen, carbon, and fluorine. They do not deplete the ozone layer, but they are potent greenhouse gases.
