1,1,1,2-Tetrafluoroethane

<p>1,1,1,2-Tetrafluoroethane (also known as norflurane (<a href="/facts/International_Nonproprietary_Name/wYL655x6">INN</a>), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a <a href="/facts/Hydrofluorocarbon/mUNTbYch">hydrofluorocarbon</a> (HFC) and <a href="/facts/Haloalkane/Enb7LQqt">haloalkane</a> <a href="/facts/Refrigerant/rI60t5zU">refrigerant</a> with thermodynamic properties similar to <a href="/facts/Dichlorodifluoromethane/KdMmfral">R-12 (dichlorodifluoromethane)</a> but with insignificant <a href="/facts/Ozone_depletion_potential/CngkPwdu">ozone depletion potential</a> and a lower 100-year <a href="/facts/Global_warming_potential/tgTbpwbJ">global warming potential</a> (1,430, compared to R-12's GWP of 10,900). It has the formula CF3CH2F and a <a href="/facts/Boiling_point/E2BK9QoS">boiling point</a> of −26.3 °C (−15.34 °F) at atmospheric pressure.  R-134a cylinders are colored <a href="/facts/Light_blue/yFW66vdf">light blue</a>.  A phaseout and transition to <a href="/facts/HFO-1234yf/gmJzRqbP">HFO-1234yf</a> and other refrigerants, with GWPs similar to CO2, began in 2012 within the automotive market.
