Chlorofluorocarbons (CFCs) Chlorofluorocarbons (CFCs) are a group of compounds which contain the elements chlorine, fluorine and carbon. At room temperatures, they are usually colourless gases or liquids which evaporate easily. They are generally unreactive and stable, non-toxic and non-flammable.

- CFCs. 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.hese then react with the ozone molecules, resulting in their removal. CFCs have a lifetime in the atmosphere of about 20 to 100 years, and consequently one free chlorine atom from a CFC molecule can do a lot of damage, destroying ozone molecules for a long time.

- But the problem with halons is they can destroy up to 10 times as much ozone as CFCs can. For this reason, halons are the most serious ozone-depleting group of chemicals emitted in British Columbia. Hydrofluorocarbons (HFCs) are being developed to replace CFCs and HCFCs, for uses such as vehicle air conditioning.

Halocarbon Halocarbon compounds are chemicals in which one or more carbon atoms are linked by covalent bonds with one or more halogen atoms (fluorine, chlorine, bromine or iodine – group 17) resulting in the formation of organofluorine compounds, organochlorine compounds, organobromine compounds, and organoiodine compounds.rganoiodine compounds, called organic iodides, are similar in structure to organochlorine and organobromine compounds, but the C-I bond is weaker. Many organic iodides are known, but few are of major industrial importance.

Perfluorocarbon Medicine. Perfluorocarbons are commonly used in eye surgery as temporary replacements of the vitreous humor in retinal detachment surgery. The length of the perfluorated carbon chain determines the physical properties of a particular perfluorocarbon.erfluorocarbons (PFCs) are compounds derived from hydrocarbons by replacement of hydrogen atoms by fluorine atoms. PFCs are made up of atoms of carbon, fluorine, and/or sulfur.

Chloroform Summary: Chloroform is a colorless liquid with a pleasant, nonirritating odor and a slightly sweet taste. It will burn only when it reaches very high temperatures. In the past, chloroform was used as an inhaled anesthetic during surgery, but it isn't used that way today.Today, chloroform is used to make other chemicals and can also be formed in small amounts when chlorine is added to water. Other names for chloroform are trichloromethane and methyl trichloride.t will burn only when it reaches very high temperatures.

Fluorocarbon Fluorocarbons, sometimes referred to as perfluorocarbons or PFCs, are, strictly speaking, organofluorine compounds with the formula C x F y, i.e. they contain only carbon and fluorine, though the terminology is not strictly followed.rior to that, fluorocarbons were prepared by reaction of fluorine with the hydrocarbon, i.e., direct fluorination. Because C-C bonds are readily cleaved by fluorine, direct fluorination mainly affords smaller perfluorocarbons, such as tetrafluoromethane, hexafluoroethane, and octafluoropropane.

Chlorofluorocarbons (CFCs) Chlorofluorocarbons enter the body primarily by inhalation of air containing chlorofluorocabons, but can also enter by ingestion of contaminated water, or by dermal contact with chlorofluorocarbons. Inhalation of high levels of chlorofluorocarbons can affect the lungs, central nervous system, heart, liver and kidneys. Symptoms of exposure to chlorofluorocarbons can include drowsiness, slurred speech, disorientation, tingling sensations and weakness in the limbs.

Best Navigation Systems This is a secure set-up in most cases, but if a car is parked in extremely hot weather, the GPS should be removed. Other mounting options are available for an extra cost. The in-car charger cord is just a simple wire, and it does have a tendency to get a bit tangled. Several owners commented that they would have preferred a curly cable.

- Chlorofluorocarbons in Insulation Materials. Most rigid-board insulation is produced with CFC-11 or -12 as the blowing agent. Injected into the foam as a liquid during manufacturing, the CFC boils, causing gas bubbles to form in the curing foam. The cured foam has bubbles of CFC gas throughout.weet. UV light breaks a chlorine atom off a CFC molecule. The chlorine reacts with ozone (O3), forming molecular oxygen (O2) and chlorine monoxide. The oxygen is pulled off that molecule by a free oxygen atom, leaving the chlorine atom to start the process all over again.
