R143a or simply trifluoroethane,Website:http://www.sinofluorine.com, is a fluorocarbon compound that is a clear, colorless gas. It is used as a refrigerant either by itself or more commonly as a component of blended mixtures. Unlike CFCs used as refrigerants, R143a has no chlorine atoms and is therefore not an ozone-depleting chemical, though its high chemical stability and infra-red absorbency make it a potent greenhouse gas. R143a is also used as a propellant in canned air products used to clean electronic equipment.NamesIUPAC name1,1,1-TrifluoroethaneOther namesMethylfluoroform, 1,1,1-Trifluoroform, R-143a, HFC-143a, UN 2035IdentifiersCAS Number420-46-2?ChemSpider9484?EC Number206-996-5Jmol?3D modelInteractive imagePubChem9868PropertiesChemical formulaC2H3F3Molar mass84.04 g/molAppearanceColourless gasDensity3.7 kg/m3?(gas)Melting point?111??C (?168??F; 162?K)Boiling point?47.6??C (?53.7??F; 225.6?K)Vapor pressure11 200 hPa (20 ?C)
