Where Is the Ozone Layer Located? A chlorofluorocarbon (CFC) is an organic compound that contains only carbon, chlorine, and fluorine, produced as a volatile derivative of methane, ethane, and propane. They are also commonly known by the DuPont brand name Freon. The most common representative is dichlorodifluoromethane (R-12 or Freon-12).

"What is ""MVC"" in a blood test?" I think you mean MCV which means a mean corpuscular volume. This is a parameter for the mean volume of the measured erythrocytes or the average red blood cell size. When the MCV is low it means your red blood cells are averagely small and this is ... This page may be out of date.

CFCs: Definition, Properties & Uses What Are CFCs? CFCs are short for the compound, chlorofluorocarbon, which contain carbon, chlorine, and fluorine. Chlorofluorocarbons are more commonly referred to as CFCs or, when used for refrigeration, CFCs are also known as freon. Developed in the 1930s as a safe alternative to ammonia, usage of CFCs grew rapidly because of its usefulness and convenience throughout most of the 20th century.

What does the EPA R-22 Phase-Out Mean to the HVAC Industry? Today, the term Freon actually refers to a wide range of refrigerant chemicals with different physical and chemical properties. By convention, refrigerant names use the letter R accompanied by a number that describes the molecular structure. Common refrigerants include R-11, R-12, R-22 and R-134A. R-22 refrigerant, the focus of the current EPA phase-out, is chemically known as chlorodifluoromethane. First introduced in the mid-twentieth century, R-22 has been the refrigerant of choice for home air conditioners for decades.

Which gas is used in Air Conditioners of today? Refrigerants make air conditioning possible. Contained within the coils of an air conditioner, these liquid agents cool and dehumidify indoor air. For years, the most common refrigerant gas used in air-conditioning systems was R-22 (Freon). Today, Services for Major Brand's Air Conditioner should be provided considering growing environmental concerns. Production of systems using R-22 refrigerant is being dropped out.

Chlorofluorocarbon Chlorofluorocarbons (CFC) are gases used for various purposes including solvents,refrigerants and aerosol sprays. They are organic chemicals and contain carbon, (sometimes hydrogen,) chlorine, and fluorine. They were much used in the middle 20th century, replacing chemicals that were toxic or flammable or had other problems. In 1978, Sweden became the first country that banned CFC products.

- window air conditioner image by Aaron Kohr from Fotolia.com. Freon is the trade name for a group of man-made chemicals called chlorofluorocarbons (CFCs). CFCs contain chlorine, fluorine and carbon and are often found in air conditioners and refrigerators. The manufacturing and use of Freons is restricted and is gradually being phased out. People are usually exposed to Freon by accidentally or deliberately breathing it in.

Chlorofluorocarbons (CFCs) Most CFCs have been released to the atmosphere through the use of aerosols containing them and as leakages from refrigeration equipment. Other releases may occur from industry producing and using them and other products containing them. There are not thought to be any natural sources of CFCs to the environment.

Freons Also known as: Chlorofluorocarbons, CFCs, Halons. Other names include: Fluorotrichloromethane, Dichlorodifluoromethane, Trichlorotrifluoroethane, Bromochlorodifluoromethane, Dibromotetrafluoroethane, Chlorodifluoromethane. Freons are colorless liquids or gases. Freons were used as coolants or pressurizers in spray can products, including drugs. In the 1970s, scientists discovered that these chemicals were destroying the earth's ozone layer. This was allowing potentially dangerous levels of ultraviolet light to reach the earth.

Where Is the Ozone Layer Located? Freon-12, for example, indicates a methane derivative (only two numbers) containing two fluorine atoms (the second 2) and no hydrogen (1-1=0). It is therefore CCl 2 F 2. Another, easier equation that can be applied to get the correct molecular formula of the CFC/R/Freon class compounds is this to take the numbering and add 90 to it. The resulting value will give the number of carbons as the first numeral, the second numeral gives the number of hydrogen atoms, and the third numeral gives the number of fluorine atoms.

Chlorofluorocarbon Chlorofluorocarbons are fully halogenated paraffin hydrocarbons that contain only carbon, chlorine, and fluorine, produced as volatile derivative of methane, ethane, and propane. They are also commonly known by the DuPont brand name Freon. The most common representative is dichlorodifluoromethane. Many CFCs have been widely used as refrigerants, propellants, and solvents.

Ozone depletion HFCs, which contain no chlorine or bromine, do not contribute at all to ozone depletion although they are potent greenhouse gases. The best known of these compounds is probably HFC-134a (R-134a), which in the United States has largely replaced CFC-12 (R-12) in automobile air conditioners.
