- Chlorofluorocarbon (CFC) is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane. A common subclass is the hydrochlorofluorocarbons (HCFCs), which contain hydrogen, as well. Freon is DuPont's brand name for CFCs, HCFCs and related compounds.

Chlorofluorocarbon 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).ecause CFCs contribute to ozone depletion in the upper atmosphere, the manufacture of such compounds has been phased out under the Montreal Protocol, and they are being replaced with other products such as hydrofluorocarbons (HFCs) (e.g., R-410A), hydrocarbons, and CO 2.

What Are CFCs? A: CFCs, also known as chlorofluorocarbons, are compounds that are most commonly used as refrigerants, propellants and solvents. Best known as Freon, CFCs have been discontinued as the main source of coolant in air conditioners and refrigerators because of their ability to deplete the ozone layer in the atmosphere.

What are chlorofluorocarbons - CFCs? CFC'S or Chlorofluorocarbons are molecules which demolish the ozone layer. The ozone layer is made up of O3 or ozone molecules these reflect UV rays (harmful ultra violet ligh … t) the CFC'S smash up the O3 into O2 molecules (the type we breathe) these do not reflect UV so we suffer.

- CF causes the body to produce an abnormally thick, sticky mucus due to the faulty transport of sodium and chloride (salt) within cells lining organs such as the lungs and pancreas to their outer surfaces. The thick CF mucus also obstructs the pancreas, preventing enzymes from reaching the intestines to help break down and digest food.

- However, CFCs damage ozone in the ozone layer when they escape into the atmosphere. This allows more ultraviolet radiation to reach the Earth’s surface. When scientists discovered that CFCs damage the ozone layer, they suggested that CFCs should be banned.FCs have some useful properties. For example: they are chemically inert (unreactive). they have a low boiling points (so they turn into gases easily). they are insoluble [insoluble: Unable to dissolve (usually in water).] in water. These properties made CFCs very useful in the past.

Chemicals What are VOCs? Volatile organic compounds are chemicals used to manufacture and maintain building materials, interior furnishing, cleaning products and personal care products. Volatile means that these chemicals evaporate or can easily get into the air at room temperature. Organic means these chemicals are carbon based. The term chemical emissions refers to VOCs as they evaporate into the air from products.

Chlorofluorocarbons (CFCs): Refrigerants that Cause Ozone Layer Depletion Chlorofluorocarbons (CFCs) have been found to cause the depletion of the ozone layer. The ozone layer prevents ultraviolet radiations of the sun from coming on the earth. This article describes the process of damaging effects of CFCs.

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.

- When UV radiation hits a CFC molecule it causes one chlorine atom to break away. The chlorine atom then hits an ozone molecule consisting of three oxygen atoms and takes one of the oxygen molecules, destroying the ozone molecule and turning it into oxygen.hilst chlorine is a natural threat to ozone, CFCs which contain chlorine are a man-made problem. Although CFC molecules are several times heavier than air, winds mix the atmosphere to altitudes far above the top of the stratosphere much faster than molecules can settle according to their weight.

What are CFC & HCFC Refrigerants? CFCs, or Chlorofluorocarbons, are the original refrigerant. They consist of Carbon, Chlorine, and Fluorine. When you hear someone say ‘Refrigerant,’ they are referring to CFCs. HCFCs, or Hydrochloroflourocarbons, are the close neighbor of CFCs. The main difference between the two types of refrigerant is that HCFCs contain one additional hydrogen atom compared to CFCs. Both CFCs and HCFCs were widely used in the twentieth century as refrigerants, propellants, and solvents.
