What Is a Chlorofluorocarbon?

CFCs (Chloro-fluoro-carbon in English) is the English abbreviation for chlorofluorocarbons. It is an artificial hydrocarbon chemical substance containing chlorine and fluorine that was invented and used in the early 1930s. It is used in the production and life of human beings. There are many uses in it.

The large-scale production and use of chlorofluorocarbons in the industry is a substance that destroys the ozone layer. According to the English name of chlorofluorocarbons, Chloro-fluoron-carbon, the acronym CFC is used to form the acronym. The CFC code is used as the collective name for chlorofluorocarbons.
The compound code is marked after CFC, which can represent different chlorofluorocarbons, such as CFC-12 for dichlorodifluoromethane and CFC-113 for 1,1,2-trichloro-1,2,2-trifluoroethane Wait.
The nomenclature of chlorofluorocarbons is that they are followed by codes to indicate different chemicals (or compositions). The coding principle is to use three digits to make up the code. The single digit indicates the number of fluorine atoms in the molecule, the tens digit indicates the number of hydrogen atoms in the molecule plus 1, and the hundredth digit indicates the single digit of the carbon atom in the molecule. Minus 1. According to this principle, the code of trichloromonofluoromethane (molecular formula is CCl3F) is 0, the tens digit is 1, the single digit is 1, and it is written as CFC -11; the dichlorodifluoromethane (molecular formula is) The code has a zero digit, a tens digit of 1, a single digit of 2, and is written as CFC-12. Several important CFC substances are listed below:
Code chemical formula chemical name
CFC-11 CCl3F trichloromonofluoromethane
CFC-12 CCl2F2 dichlorodifluoromethane
CFC-13 CClF3 Monochlorotrifluoromethane
CFC-113 CCl2FCClF2 Trichlorotrifluoroethane
CFC-114 CClF2CClF2 Dichlorotetrafluoroethane
CFC-115 CClF2CF3 Monochloropentafluoroethane
The above substances are also called perchlorofluorocarbons because the hydrogen atoms connected to carbon are completely replaced by chlorine and fluorine.
