Sulfur hexafluoride | F6S - PubChem 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).
Study on Pyrolysis Characteristics of SF6 in a Trace ... ReaxFFSFO force field for a SF6–O2 system is developed based on the density functional theory (DFT) calculation data. Then, a series of molecular dynamics (MD) simulations were performed. The results show that the main oxygen-containing compounds that appeared in the MD simulation include SOF4, SOF2, and SO2F2. The relative quantitative relationship between SOF2 and SOF4 can be …
