| has gloss | (noun) a fluorocarbon with chlorine; formerly used as a refrigerant and as a propellant in aerosol cans; "the chlorine in CFCs causes depletion of atmospheric ozone" chlorofluorocarbon, CFC |
| has gloss | eng: A 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. They are also commonly known by the DuPont trade name Freon. The most common representative is dichlorodifluoromethane (R-12 or Freon-12). Many CFCs have been widely used as refrigerants, propellants (in aerosol applications), and solvents. The manufacture of such compounds is being phased out by the Montreal Protocol because they contribute to ozone depletion. |
| has gloss | eng: Chlorofluorocarbons (CFC) are gases used in refrigerant and aerosols: a gas containing carbon, (sometimes hydrogen,) chlorine, and fluorine, used as a refrigerant and aerosol propellant. In 1978, Sweden became the first country that banned CFC products. Later, the US and Canada did the same. Nowadays, in most countries the use of CFC products is not allowed, because they are destroying the ozone layer. CFCs also are greenhouse gases, creating a natural-made greenhouse effect. |

| has gloss | dan: CFC-gasserne (forkortelse for Chloro-Fluoro-Carbon) er en gruppe af kunstigt fremstillede kemiske forbindelser, som består af klor, fluor og kulstof. De blev tidligere brugt overalt i f.eks. køleskabe og som drivgas i sprayflasker eller som rensemidler. I det store og hele er det forbudt at bruge dem ifølge Montrealaftalen, da man er overbevist om, at de har skadelig virkning på ozonlaget. Som erstatning bruges HCFC (Hydro-chloro-fluoro-kulstoffer), der spaltes i de laveste lag af atmosfæren, men som desværre fører til opbygning af stigende mængder klor i atmosfæren. Af samme grund fortsætter forsøgene på at finde nye og bedre erstatninger. |

| has gloss | deu: Fluorchlorkohlenwasserstoffe (FCKW), chemische Nomenklatur nach IUPAC: Chlorfluorkohlenwasserstoffe (CFKW), sind eine umfangreiche chemische Gruppe niedermolekularer organischer Verbindungen, die als Treibgase oder Kältemittel verwendet werden. FCKW sind Kohlenwasserstoffe, bei denen Wasserstoffatome durch die Halogene Chlor und Fluor ersetzt wurden, sie sind eine Untergruppe der Halogenkohlenwasserstoffe. FCKW, die nur Einfachbindungen enthalten, nennt man gesättigte FCKW. Ist in der Verbindung kein Wasserstoff mehr enthalten, so nennt man sie Chlorfluorkohlenstoffe. Im Laufe der 70er und 80er Jahre des 20. Jh. stellte sich heraus, dass die Freisetzung von FCKW in die Atmosphäre in erheblichem Maße für den Abbau der Ozonschicht in der Stratosphäre (Ozonloch) verantwortlich ist, weshalb der Einsatz von FCKW heute in vielen Anwendungsbereichen verboten ist. |

| has gloss | fin: CFC-yhdisteet ovat kemiallisia yhdisteitä, jotka muodostuvat kloorista, fluorista ja hiilestä. Klooratut ja/tai fluoratut hiilivedyt ovat molekyylipainoltaan pieninä yhdisteinä kaasumaisia, pidempinä ketjuina nestemäisiä tai vahamaisia ja pitkinä polymeereina muoveja, kuten teflon. Yhteistä näille kemikaaleille on se, että ne ovat hyvin inerttejä aineita, jotka eivät helposti reagoi muiden kemikaalien kanssa, ja ovat siten myös turvallisia ihmiselle. |

Disse stoffene har vært svært populære som kuldemedier på grunn av ingen giftighet og høy stabilitet. De har også vært brukt som rensemiddel og drivmiddel i spraybokser. KFK-stoffene er nå langt på vei forbudt, og erstattet av hydroklorfluorkarboner (HKFK) (også med restriksjoner), hydrofluorkarboner (HFK) og naturlige stoffer som hydrokarboner, ammoniakk og karbondioksid. Forbudet kom som del av Montreal-protokollen som tiltak for å unngå reduksjon av ozon-laget i den øvre atmosfære. |
