R134a (1,1,1,2-Tetrafluoroethane, HFC134a, Norflurane) CAS:811-97-2

R134a

R134a (1,1,1,2-Tetrafluoroethane), R-134a, Genetron 134a, Suva 134a, HFC-134a, HFC134a, Dymel 134a or Norflurane, is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential.

Uses

R134a is an inert gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. These devices began using R134a in the early 1990s as a replacement for the more environmentally harmful R-12, and retrofit kits are available to convert units that were originally R-12-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. R134a has also been used to cool computers in some overclocking attempts. It is also commonly used as a propellant for airsoft airguns.
R134a is also being considered as an organic solvent suitable for extraction of flavor and fragrance compounds, as a possible alternative to other organic solvents and supercritical carbon dioxide. It can also be used as a solvent in organic chemistry, both in liquid and supercritical fluid. It is used in the resistive plate chamber particle detectors in the Large Hadron Collider. It is also used for other types of particle detectors, e.g. some cryogenic particle detectors. It can be used as an alternative to sulfur hexafluoride in magnesium smelting as a shielding gas.
R134a is also being considered as an alternative to sulfur hexafluoride as a dielectric gas. Its arc-quenching properties are poor, but its dielectric properties are fairly good.
An additional use of R134a is as a propellant. It is used in this way mainly for gas-powered airsoft guns. The gas is often mixed with a silicon-based lubricant to assist with maintaining functionality of the airsoft gun.
