Quick Detail:
1, 1, 1, 2-Tetrafluoroethane, R-134a or HFC-134a, is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with less ozone depletion potential. 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.
Description:
R134a, 1, 1, 1, 2-Tetrafluoroethane first appeared in the early 1990s as a replacement for dichlorodifluoromethane (R-12), which has ozone depleting properties. 1, 1, 1, 2-Tetrafluoroethane has been atmospherically modeled for its impact on depleting ozone and as a contributor to global warming. Research suggests that over the past 10 years the concentration of 1, 1, 1, 2-tetrafluoroethane has increased significantly in the Earth\'s atmosphere, with a recent study revealing a doubling in atmospheric concentration between 2001 and 2004.
