  • 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).

  • Porous Organic Cages for Sulfur Hexafluoride Separation

    Sulfur hexafluoride (SF 6) is a much more potent greenhouse gas than CO 2, with an estimated atmospheric lifetime of 800–3200 years. The Intergovernmental Panel on Climate Change found SF 6 to be the most potent greenhouse gas that it evaluated, with a global warming potential 23,900 times higher than CO 2. Nonetheless, SF 6 has valuable and widespread industrial uses.
