摘要：

The ionization and solution enthalpies of the nitrophenol isomers were measured calorimetrically at 25°C in water-DMSO mixtures ranging from pure water up to 0.8 DMSO mole fraction. The different solvation values obtained for ortho-nitrophenol with respect to the meta and para isomers, were explained taking into account the electrostatic forces between the water molecules and the anions, as well as the intramolecular and intermolecular hydrogen bonds associated with the undissociated molecules. © 1978.
