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.

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.
