Abstract
Isentropic compressibility, its excess value, excess molar volume, excess viscosity, and excess molar free energy for the activation of flow have been calculated from the experimental values of the speed of sound, density and viscosity at 298.15 and 308.15 K for mixtures of prop-2-en-1-ol with ethylbenzene or isopropylbenzene. The parameter d, of the Grunberg and Nissan expression, has also been calculated. The variation of the excess functions with composition indicates the absence of any specific interactions. In both the systems at 298.15 K, for alcohol mole fraction less than 0.66, the dissociation of the hydrogen-bonded alcohol agglomerates predominates over the association between unlike molecules. At the higher temperature the dissociation is predominant over the whole composition range.
