Synthesis and ReactionsApplicationsGreenhouse GasPhysiological Effects and PrecautionsOther PropertiesSee AlsoFurther ReadingExternal Linkssf 6 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 scrubbing the product with NaOH to destroy remaining SF4. There is virtually no reaction chemistry for sf 6. A main contribution to the inertness of sf6 gas is the steric hindrance of the sulfur atom, whereas its heavier group 16 counterparts, such as SeF6 are more reactive than sf 6 as a result of less steric hindrance (See hydrolysis example). It does not react with molten sodium, but reacts exothermically with lithium.Get price

Global warming potential - Wikipedia

Global warming potential (GWP) is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide (CO 2). GWP is 1 for CO 2. For other gases it depends on the gas and the time frame. Carbon dioxide equivalent (CO 2 e or CO 2 eq or CO 2-e) is calculated from GWP. ItGet price

Properties - American Chemical Society

In the context of contributions of different gases to atmospheric warming the concept of global warming potential (GWP) can be useful. GWP is a measure of how much energy a greenhouse gas would add to atmospheric warming in a given time compared to CO 2. A molecule’s GWP depends on three factors: the wavelengths where the molecule absorbs.Get price
