• Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

  • Sulfur hexafluoride (Sulfr hexafluoride) emission estimates for China: an

    Sulfur hexafluoride (sf 6) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, Sulfr hexafluoride emissions from China were inventoried for 1990-2010 and projected to 2020. Results reveal that the highest sf 6 emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the gaz sf6 production sector (each about 10%).

    The development of new methods for the chemical activation of the extremely inert greenhouse gas sulfur hexafluoride (SF 6) not only is of current environmental interest, but also offers new opportunities for applications of SF 6 as a reagent in organic synthesis. We herein report the first nucleophilic activation of SF 6 by Lewis bases, namely by phosphines, which results either in its complete degradation to phosphine sulfides and difluorophosphoranes or in the selective conversion of SF 6
