05/01/2015To accurately size control valves for gas service, and give the flow graph is correct shape, an Expansion Factor (symbol Y) is added to the equation we started with earlier, to correct the calculated flow (and the graph) for both changes in density at the vena contracta and for vena contracta enlargement. The equation shown here for Y is based on experimental observation of what actually happens.

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 SF6. It does not react with molten sodium. Starting from SF4, one can prepare SF5Cl, which is structurally related to SF6.
