Hydration of Some Acids in Sulfolane
Keyword(s):
Interaction between water at low concentrations and some carboxylic acids, methane-sulfonic acid and picric acid, HA, have been studied in Sulfolane at 30 °C. Vapor pressure measurements and calorimetry were used. Results are interpreted in terms of hydration constants K1 and enthalpy changes ΔH1, for the 1:1 complexes [Formula: see text] The values of K1 are low and generally increase slightly with the strength of the acid HA from ∼0.4 for acetic acid to 5.7 for methanesulfonic acid.
