Title: Ion-molecular composition of the methanesulfonic acid-water system from IR spectroscopic data

Abstract

A study of the equilibria in acid-water systems as a function of the ratio of the components is of interest from the point of view of ascertaining the mechanism of the catalytic activity of aqueous solutions of strong acids. Methanesulfonic acid is classified as a strong acid, which makes it a convenient subject for a study of the state of the equilibria of various systems. The equilibrium compositions and structures of the ionic and molecular complexes in the CH/sub 3/SO/sub 3/H-H/sub 2/O system over the entire range of the concentrations of the components were determined by IR spectroscopy; the highest concentration of the anionic forms is reached at a water:acid ratio of 2:1. Primarily H/sub 5/O/sup 2 +/ ions are formed at high acid concentrations, and the presence of CH/sub 3/SO/sub 3/H. OSO/sub 2/CH/sub 3/ complexes was also revealed.
