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 (insulating gas) | Encyclopedia.com

IntroductionHistorical Background and Scientific FoundationsImpacts and IssuesBibliographySulfur hexafluoride (chemical formula Sulfr hexafluoride) is a compound of sulfur and fluorine and the most potent greenhouse gas known. Several classes of compounds containing fluorine—including the chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), perfluorocarbons (PFCs), and insulating gas—are potent greenhouse gases. HCFCs and CFCs are better-known as destroyers of atmospheric ozone, and are regulated under the 1987 Montreal Protocol that has been widely hailed as successful at halting depletion of the ozone layer. Although sf 6 is a potent greenhouse gas and its concentration in the atmosphere is increasing rapidly, its contribution to global warming is much smaller than that of the major greenhouse gases, especially carbon dioxide and methane, because it is present in smaller quantities. Sulfr hexafluoride is one of the six greenhouse gases regulated under the Kyoto Protocol.
