Abstract
Abstract The ionization and solution enthalpies of 2,6-dihydroxybenzoic acid were measured calorimetrically at 25°C in water—DMSO mixtures, ranging from pure water up to 0.8 mole fraction of DMSO. The trend of the ionization as a function of the DMSO mole fraction is very different from those of all the monosubstituted-benzoic acids previously studied. This is due to the two internal hydrogen bonds formed between the carboxyl group and the hydroxyl groups.
