Chlorofluorocarbon - Wikipedia
Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane. The most common example is dichlorodifluoromethane (R-12). R-12 is also commonly called Freon and ...

Chlorofluorocarbon (CFC) – Definition, Formulas, Examples
Sources of CFC. a) Refrigerators and air conditioners – Refrigerants are the most common emitter of CFC. If the coolant used in refrigerators, air conditioners, cars, are not properly disposed it will leak CFCs in the atmosphere. Either the coolant will evaporate or get into the soil, contaminating both with CFC.
Chlorofluorocarbons and Ozone Depletion - American Chemical Society
2017年4月18日 · At the University of California, Irvine, F. Sherwood Rowland and Mario J. Molina discovered that chlorofluorocarbons (CFCs) could deplete Earth’s atmospheric ozone layer, which blocks the sun’s damaging ultraviolet rays.
What are Chlorofluorocarbons (CFCs)? - Energy Theory
2023年11月17日 · The following are some significant CFC examples: CFC-11 (Trichlorofluoromethane): CFC-11 known as freon-11 or R-11 is a colourless liquid with a slight ethereal and sweet odour. It boils at room temperature damaging the ozone layer. CFC-12 (Dichlorodifluoromethane): CFC-12, a colourless gas, is commonly marketed under the brand name Freon-12 ...

CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms. Individual CFC molecules are labeled with a unique numbering system. For example, the CFC number of 11 indicates the number of atoms of carbon, hydrogen, fluorine, and chlorine (e.g. CCl 3 F as CFC-11). The best way to remember the system is ...
Chlorofluorocarbon (CFC) | Britannica
2024年10月8日 · Chlorofluorocarbon (CFC), any of several organic compounds composed of carbon, fluorine, and chlorine. When CFCs also contain hydrogen in place of one or more chlorines, they are called hydrochlorofluorocarbons, or HCFCs. CFCs are also called Freons, a trademark of the E.I. du Pont de Nemours &.
Chlorofluorocarbons (CFCs) - Structure, Properties, Applications …
CFC stands for chlorofluorocarbon, which is an organic compound made up of carbon, fluorine, and chlorine. Hydrochlorofluorocarbons, or HCFCs, are CFCs that also contain hydrogen in place of one or more chlorines. CFCs are also known as Freons, a brand of Wilmington, Delaware-based E.I. du Pont de Nemours & Company.
Chlorofluorocarbon - an overview | ScienceDirect Topics
Chlorofluorocarbons (CFCs) are synthetic organic compounds that contain chlorine and fluorine. They are known for their ability to deplete stratospheric ozone and were eliminated from use under the Montreal Protocol. CFCs are clear, colorless liquids or gases with a slight etherlike odor at high concentrations.
