1,1-Difluoroethane - Wikipedia
WEB1,1-Difluoroethane, or DFE, is an organofluorine compound with the chemical formula C 2 H 4 F 2. This colorless gas is used as a refrigerant, where it is often listed as R-152a (refrigerant-152a) or HFC-152a (hydrofluorocarbon-152a). It is also used as a propellant for aerosol sprays and in gas duster products.
