31 results about "Fluoroantimonic acid" patented technology

Fluoroantimonic acid is an inorganic compound with the chemical formula H₂FSbF₆ (also written H₂F[SbF₆], 2HF·SbF₅, or simply HF-SbF₅). It is an extremely strong acid, easily qualifying as a superacid. The Hammett acidity function, H₀, has been measured for different ratios of HF:SbF₅. While the H₀ of pure HF is −15, addition of just 1 mol % of SbF₅ lowers it to around −20. However, further addition of SbF₅ results in rapidly diminishing returns, with the H₀ reaching −21 at 10 mol %. The use of an extremely weak base as indicator shows that the lowest attainable H₀, even with > 50 mol % SbF₅, is somewhere between −21 and −23.
