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)People also search forsulfur hexafluoride medicationsulfur hexafluoride symbolsulfur hexafluoridesulfur hexafluoride equationsulfur hexafluoride formulasulfur hexafluoride voiceCN101857202A Purification method of sulfur hexafluoride and … patents.google/patent/CN101857202A/enThe invention discloses a purification method of sulfur hexafluoride and equipment thereof.
