  • Sulfur hexafluoride | F6S - PubChem

    Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

  • Sulfur hexafluoride - Wikipedia

    Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S 2 F 10 (which is highly toxic) and then scrubbing the product with NaOH to destroy remaining SF 4. Alternatively, utilizing bromine, sulfur hexafluoride can be synthesized from SF 4 and CoF 3 at lower temperatures (e.g. 100 &C), as follows:
