Abstract
The enthalpies of solutions of tetraethylammonium and tetrabutylammonium bromides in the water-rich region of the water–acetone and water–hexamethyl phosphoric triamide mixed solvents have been measured at 25°C using a precise calorimetry system. The enthalpies of electrolyte solutions at infinite dilution were calculated using the Debye–Hückel theory. The enthalpies of solute transfer from water to the mixtures with acetone and hexamethyl phosphoric triamide were calculated. The enthalpy coefficients of solute–pair interactions with hexamethyl phosphoric triamide and acetone in aqueous solution were obtained using the McMillan–Mayer formalism. The values obtained were compared with those for other organic cosolvents. It was found that in aqueous solution the solutes show a strong tendency for hydrophobic interaction with cosolvent molecules, particularly in the water–hexamethyl phosphoric triamide system.
