Pentafluoroethane (original) (raw)
Pentafluorethan je organická sloučenina, derivát ethanu, u kterého je pět vodíkových atomů nahrazeno atomy fluoru. I když není škodlivý pro ozonovou vrstvu, jeho potenciál globálního oteplování je 3450krát větší než u oxidu uhličitého (dle americké Agentury pro ochranu životního prostředí). Pentafluorethan smíchaný s difluormethanem v poměru 1:1 se označuje jako R-410A, což je běžná náhrada za freony v nových chladicích zařízeních. Pentafluorethan se také často používá jako zpomalovač hoření.

(de) Le pentafluoroéthane (1,1,1,2,2-pentafluoroéthane en nomenclature IUPAC, bien qu'il ne puisse avoir d'isomère), HFC-125, ou R-125, est un réfrigérant incolore et ininflammable de la famille des hydrofluorocarbures. Il s'agit d'une molécule d'éthane dont cinq des six atomes d'hydrogène ont été substitués par des atomes de fluor. Sa formule est C2HF5, sa formule semi-développée CF3CHF2. (fr) Pentafluoroethane is a fluorocarbon with the formula CF3CHF2. Pentafluoroethane is currently used as a refrigerant (known as R-125) and also used as a fire suppression agent in fire suppression systems. Pentafluoroethane does not deplete ozone so it has replaced earlier fluorinated chemicals that did. However while it has zero ozone depletion potential, it has high global warming potential, reported by the United States Environmental Protection Agency (EPA) as 3450 times that of carbon dioxide. (en) ペンタフルオロエタン（Pentafluoroethane, 化学式：CF3CHF2），としても知られているR-125，は冷媒です。 そのオゾン破壊係数（ODP）は0ですが、地球温暖化係数（GWP）は高いです。アメリカ合衆国環境保護庁の報告によると、そのGWPは二酸化炭素の3450倍です。 (ja) Il pentafluoroetano (identificato dagli standard internazionali come HFC 125 o come NAF S 125 o R-125) è un idrofluorocarburo gassoso fluorurato, utilizzato come fluido refrigerante (in particolare è adatto per applicazioni a saturazione totale) o come agente estinguente. Tra tutti gli agenti estinguenti alogenati a zero ODP, il NAF S 125 è quello che richiede la più bassa concentrazione di spegnimento in peso. Grazie alle sue caratteristiche fisiche, molto simili a quelle dell', il NAF S 125 può essere impiegato anche per la protezione dei rischi a temperatura sotto zero. Con un punto di ebollizione di –48.5 °C, il NAF S 125 si distribuisce rapidamente ed in modo uniforme all'interno dell'ambiente protetto anche a temperature ben al di sotto dei 0° ed in presenza di ostacoli. Utilizzato nei caccia dall'aviazione statunitense, è considerato dalla Federal Aviation Administration una delle alternative all'Halon 1301 più interessanti per il settore dell'. Grazie ad una bassa tossicità acuta, NAF S 125 è idoneo all'utilizzo in aree normalmente occupate. Il massimo tempo di esposizione alle varie concentrazioni del NAF S 125 è stato calcolato dalla U.S. EPA con il modello PBPK. Nello Standard NFPA 2001 (Edizione 2000), il limite all'esposizione di NAF S 125 è fissato all'11.5% per 5 minuti. (it) Pentafluorethaan, HFK-125 of HFC-125 is een gasvormige gefluoreerde koolwaterstof. Het is een onbrandbaar gas en zwaarder dan lucht. Het heeft geen ozonafbrekend vermogen, maar wel een hoog aardopwarmingsvermogen: 3.500 keer dat van koolstofdioxide.
