Synthesis and ChemistryApplicationsGreenhouse GasNotable CharacteristicsPhysiological Effects and PrecautionsReferencesFurther ReadingSee Alsogaz sf6 can be prepared from the elements, that is exposure of S8 to F2. Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S2F10 and then scrubbing the product with NaOH to destroy remaining SF4. There is virtually no reaction chemistry for Sulfr hexafluoride. It does not react with molten sodium. Starting from SF4, one can prepare SF5Cl, which is structurally related to Sulfr hexafluoride.
