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 scrubbing the product with NaOH …See more on en.wikipedia.orgEC Number: 219 854 2RTECS number: WS4900000Gmelin Reference: 2752UN number: 1080Controlled decomposition of SF6 by electrochemical reduction beilstein journals.org/bjoc/content/pdf/1860 5397 16 244.pdfPDF filethrough the reductive activation of sulfur hexafluoride with TEMPO [23].
