fluorocarbons

[floo͡r′ōkär′bəns]
Etymology: L, fluere, to flow, carbo, coal
hydrocarbons where some or all of the hydrogens are replaced by fluorine. Fluorocarbons are generally colorless, nonflammable gases, but some are liquids at room temperature. The compounds can produce mild upper respiratory tract irritation, and excessive exposure has been cited as a cause of central nervous system depression.

fluorocarbons

Various organic compounds in which fluorine replaces hydrogen. The fluorocarbons are widely used as aerosol propellants, refrigerants and solvents and their release into the atmosphere is believed to offer a grave threat to the ecology of the planet because of their catalytic effect on the ozone layer. See also CHLOROFLUOROCARBONS.
