Synthesis and ReactionsApplicationsGreenhouse GasPhysiological Effects and PrecautionsSee AlsoFurther ReadingExternal LinksSulfur hexafluoride on Earth exists primarily as a man made industrial gas and has also been found to occur naturally. SF6 can be prepared from the elements through exposure of S8 to F2. This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901. Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S2F10 (which is highly toxic) and then scrub…See more on en.wikipedia.orgChemical formula: SF₆Molar mass: 146.06 g/molMelting point: −64 &C; −83 &F; 209 KSolubility in water: 0.003% (25 &C)Missing:standard WayMust include:standard WayImages of High Speed Rail Sulfur Hexafluoride Standard Way bing/imagesSee allSee all imagesHigh Speed Rail American Public Transportation Association apta/wp content/uploads/High Speed Rail Sustainability...PDF file7 High Speed Rail and Sustainability 2 Introduction This publication is launched by UIC, the International Union of Railways a.The UIC, founded in 1922 in Paris, today unites about 200 rail companies from 5 continents (see Figure 1).
