THERMAL DECOMPOSITION OF sf 6 AND insulating gas-AIR MIXTURES IN

Jan 01, 2013 · What causes the decomposition of sulfur fluoride on glass is the presence of H 2 0. The surface of the glass separator is always kept under vacuum in a flow of dried helium gas. So, the catalytic effect of "absent" H 2 0 should not occur. 419 K. BAUCOM: S0 2 and SOF2 can react with F 2 to form S0 2 F 2 and SOF4, respectively.Get price

8 to F 2. 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 S 2 F 10 (which is highly toxic) and then scrubbing the product with NaOH to destroy remaining SF 4.Get price

Sulfur hexafluoride purification from mixtures with air: a

Liquefaction appears to be a good method for recovering about 90% of the SF/sub 6/ if it is badly contaminated (15% air), and an even greater fraction can be recovered from mixtures containing less air. In cases where liquefaction is insufficient by itself, adsorption of SF/sub 6/ on activated carbon at -50/sup 0/F is promising.Get price
