1,1,1,2-Tetrafluoroethane (also known as norflurane (INN), R-134a, Freon
134a, Forane 134a, Genetron 134a, Florasol 134a, Suva 134a, or
HFC-134a) is a haloalkane refrigerant with thermodynamic properties
similar to R-12 (dichlorodifluoromethane) but with insignificant ozone
depletion potential and a somewhat lower global warming potential
(1,430, compared to R-12's GWP of 10,900). It has the formula CH2FCF3
and a boiling point of -26.3 °C (-15.34 °F) at atmospheric pressure.
R-134a cylinders are colored light blue. Attempts at phasing out its
use as a refrigerant with substances that have lower global warming
potential, such as HFO-1234yf, are underway.
