Synthesis and ReactionsApplicationsGreenhouse GasPhysiological Effects and PrecautionsOther PropertiesSee AlsoFurther ReadingExternal LinksSulfr hexafluoride 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 Sulfr hexafluoride. 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 Sulfr hexafluoride as a result of less steric hindrance (See hydrolysis example). It does not react with molten sodium, but reacts exothermically with lithium.Get price

Greenhouse gas emissions - Wikipedia

Greenhouse gas emissions are emissions of greenhouse gases that cause climate change by creating a greenhouse effect in the earthatmosphere.

IntroductionSafetyUsesPropertiesOzone presents itself in two forms, stratospheric and tropospheric. Stratospheric ozone occurs naturally. Tropospheric ozone, however, is a greenhouse gas that contributes to climate change. Humans produce this gas through industrial plants, chemical solvents, and burning fossil fuels. Prior to industrialization, tropospheric ozone was concentrated at 25 parts per billion in the atmosphere. Today, it is at approximately 34 parts. When O3 mixes with carbon monoxide, the combination results in smog. Taking public transportation, avoiding pesticides, and buying natural cleaning products are all ways to reduce ozone production. Nitrogen trifluoride is produced by industrial gas and chemical companies. It is recognized by the Kyoto Protocol as a greenhouse gas that contributes to global climate change. It has an atmospheric life of between 550 and 740 years. Under this environmental treaty, member countries have committed to reducing emissions of this gas.Get price
