WebIl fluorometano o fluoruro di metile [2] è un alometano monosostituito e in particolare un alogenuro alchilico, avente formula CH 3 F. È anche il più semplice degli idrofluorocarburi e può essere considerato l'estere metilico dell' acido fluoridrico. Come fluido refrigerante è commercialmente noto anche con le sigle Freon-41 e HFC-41. WebA differenza di altri gas (inclusa la CO 2), Gli HFC hanno una durata piuttosto breve rispetto ad altri gas serra più problematici per il clima, tuttavia il loro potenziale di riscaldamento globale (GWP - 100 anni) corrisponde in media a 2.800 volte quello dell'anidride carbonica (CO 2), che va da un fattore di 140 ( HFC-152a) a un fattore di 11.700 ( HFC-23).
