Partial Molar Enthalpies of Benzene and Water in Tetraethylene Glycol Dodecyl Ether-decane Solutions
Abstract
Heats of solution at 25°C are reported for benzene and water in mixtures of decane and tetraethylene glycol dodecyl ether, and in solutions containing the other solute component, in order further to clarify the interaction of benzene and water with nonionic surfactants in nonpolar media. The results suggest that benzene molecules are distributed between sites adjacent to the hydrophilic part of the surfactants and hydrophobic regions of the solution, with some preference for hydrophilic regions, while water molecules interact almost exclusively with the hydrophilic portion of the surfactant molecules. Competition between water and benzene for hydrophilic groups is demonstrated by a positive effect on the enthalpies of solution of each component by addition of a small amount of the other solute component. © 1983.
