1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...
It operates at similar pressures and possesses similar volumetric refrigerating effect to R-12 and R-134a. It can be used in a R12 or R134A compressor or a specific CARE 30 compressor. It can be used with R-12 or R-134a heat exchangers and expansion devices. It is compatible with most common refrigeration materials and lubricants.
From 1930 to 1935, they developed dichlorodifluoromethane (CCl 2 F 2 or R12), trichlorofluoromethane (CCl 3 F or R11), chlorodifluoromethane (CHClF 2 or R22), trichlorotrifluoroethane (CCl 2 FCClF 2 or R113), and dichlorotetrafluoroethane (CClF 2 CClF 2 or R114), through Kinetic Chemicals which was a joint venture between DuPont and General Motors.
It is possible to convert Freon-11 into three dimensional graphene through chemical treatment involving magnesium powder. Injecting CCl 3 F (Freon-11) into an argon filled container and across the surface of molten magnesium powder allows the chemicals to undergo a reduction reaction that creates three dimensional graphene.
