A dynamic n.m.r. study of the acidity of super-acid media (mixtures of HSO3F and SbF5 from 0 to 90 mol % of SbF5)

Abstract

Rates of proton exchange between fluoro-sulphuric acid and protonated solute bases were used to derive pK differences between the bases and the approximate course of an H0 function between 0 and 90 mol % of SbF5; the acidity increases monotonically ovre this range.
