Description
Quick Detail: 1,1,1,*-Tetrafluoroethane, R***4a or HFC***4a, is a
haloalkane refrigerant with thermodynamic properties similar to
R**2 (dichlorodifluoromethane) but with less ozone depletion
potential. It has the formula CH2FCF3 and a boiling point of
−*6.3 °C (−*5.*4 °F) at atmospheric pressure. R***4a
cylinders are colored light blue. Description:
R**4a,1,1,1,*-Tetrafluoroethane first appeared in the early ***0s
as a replacement for dichlorodifluoromethane (R**2), which has
ozone depleting properties. 1,1,1,*-Tetrafluoroethane has been
atmospherically modeled for its impact on depleting ozone and as a
contributor to global warming. Research suggests that over the past
*0 years the concentration of 1,1,1,*-tetrafluoroethane has
increased significantly in the Earth\'s atmosphere, with a recent
study revealing a doubling in atmospheric concentration between
***1 and ***4. UN Number ***9 CAS Number *******2 Application:
R**4a,1,1,1,*-Tetrafluoroethane is an inert gas used primarily as a
"high-temperature" refrigerant for domestic refrigeration and
automobile air conditioners. These devices began using
1,1,1,*-tetrafluoroethane in the early ***0s as a replacement for
the more environmentally harmful R**2 and retrofit kits are
available to convert units that were originally R***-equipped.
Other uses include plastic foam blowing, as a cleaning solvent, a
propellant for the delivery of pharmaceuticals (e.g.
bronchodilators), wine cork removers, gas dusters and in air driers
for removing the moisture from compressed air.
1,1,1,*-Tetrafluoroethane has also been used to cool computers in
some overclocking attempts. It is also commonly used as a
propellant for airsoft airguns. Specifications: Property of
