Trifluoromethyl Sulfur Pentafluoride Trifluoromethyl sulfur pentafluoride (SF5CF3), which is a newly discovered compound in the troposphere and chemically similar to SF6, has been listed as a potent greenhouse gas because of its high global warming potential close to 20,000 and its long lifetime of about 800 years in the atmosphere. DMSO is a commercially manufactured dipolar aprotic solvent which is also a naturally occurring substance. It is apparently a part of earth’s complex sulfur cycle. DMSO is created in the atmosphere at a rate of 20-60 billion pounds per year from dimethyl sulfide, which is produced by metabolic processes in soil and sediments.

Trifluoromethyl sulfur pentafluoride CF 3 SF 5: ppt ~1000 * The Ozone Depletion Potentials (ODP) is typically used to contrast different gases and provides a simple ... We find that C 8 F 18 's radiative efficiency is similar to trifluoromethyl sulfur pentafluoride's (SF 5 F 3) at 0.57 W m −2 ppb −1, which is the highest radiative efficiency of any measured atmospheric species.

Also known as 1,1,3,3,3-pentafluoro-2-(trifluoromethyl)-1-p ropene (CAS Registry Number 382-21-8) or PFIB, perfluoroisobutene is a rapidacting lung irritant that damages the air-blood barrier of the lungs and causes oedema. 摘要： In this paper, we verified Sturge's speculation (Science, 2000) that SF5CF3 might originate as a breakdown product of SF6 in high-voltage equipment via the spark discharge reactions of SF6 with a few fluorocarbons, such as CHF3 and CH,F,. Global warming potential The values of global warming potentials for GHGs to be used in calculations shall be in accordance with Table B.1 (IPCC 2007, Table 2.14, see Clause 2).

The researchers find the gas, trifluoromethyl sulfur pentafluoride ([SF.sub.5][CF.sub.3]), only at trace levels--about 0.12 parts per trillion in 1999--in the atmosphere, but their analysis shows that concentrations are rising at about 6 percent per year. identified as trifluoromethyl sulfur pentafluoride (SF 5CF 3), has been detected in the atmosphere [10,11]. It is supposed that SF 5CF 3 originates as a breakdown product of SF 6 formed by high-voltage discharges in electric industry equipment . Atmospheric lifetime of SF 5CF 3 (~800

Aug 20, 2006 · When more than two dozen countries undertook in 1989 to fix the ozone hole over Antarctica, they began replacing chloroflourocarbons in refrigerators, air conditioners and hair spray. But they had little idea that using other gases that contain chlorine or fluorine instead also would contribute greatly to global warming.
In 2000 scientists identified a substantial rise in atmospheric concentrations of a newly identified synthetic compound called trifluoromethyl sulfur pentafluoride. Atmospheric concentrations of this gas are rising quickly, and although it still is extremely rare in the atmosphere, scientists are concerned because the gas traps heat more ... name cas formula inchikey aliases identified as trifluoromethyl sulfur pentafluoride (SF 5CF 3), has been detected in the atmosphere [10,11].

Atmospheric lifetime of SF 5CF 3 (~800 Of course, nitrogen dioxide has a global warming potential (GWP) of 296—where carbon dioxide is 1—hydrofluorocarbon HFC-23 is rated 12,000, trifluoromethyl sulfur pentafluoride is 18,000 and sulfur hexafluoride, used as a high voltage insulator, has a GWP of 22,200. Thankfully, there are only trace amounts of those gases in the air.
