Norflurane (1,1,1,2-Tetrafluoroethane) is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. 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. Liquid Norflurane absorbs a high amount of thermal energy from the environment during its evaporation at atmospheric pressure. Norflurane is commercially available as a liquid in pressurized cylinders or cans. Norflurane is used as a propellant for some metered dose inhalers and as an inhalational anesthetic agent in animal studies.

PRIMARY | 1,1,1,2-tetrafluoroethane, R-134a, Forane 134a, Genetron 134a, Florasol 134a, Suva 134a or HFC-134a, also known as norflurane (INN), is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant 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.[2] Attempts at phasing out its use as a refrigerant with substances that have lower global warming potentials, such as HFO-1234yf are underway. |
