Abstract
In concentrated solutions of methylsulfonic acid in butyl acetate (BA), molecular and ionic complexes were found to be in equilibrium: $$ AH \cdots B \cdots HA + HA \leftrightarrow AH \cdots BH^ + + (AHA)^ - . $$ The base is fully protonated only at a more than 10-fold excess of the acid. In the presence of tetrachloroethane (TCE), a neutral solvent, the IR spectra of the system are indicative of an increase in the concentration of undissociated acid molecules (HA) and a decrease in the concentration of proton solvates (AHA)−. This means that the equilibrium shifts to the formation of molecular structures. At C TCE 0 :C BA 0 > 2, TCE molecules attenuate the promoting effect of undissociated acid molecules, which are known to facilitate the transfer of a proton to a base molecule with the formation of an (AHA)− ion with a strong symmetrical H-bond.
