ABSTRACT
Excess molar volumes, , excess molar isentropic compressibilities, , and deviations of the speeds of sound, , from their ideal values in an ideal mixture for binary mixtures of 1-octanol, C8H17OH with hexadecane, C16H34 and squalane (2,6,10,15,19,23-hexamethyltetracosne), C30H62 at T = (298.15, 303.15, and 308.15) K and at atmospheric pressure were derived from experimental density, , and speed-of-sound data, . Viscosity measurements were also carried out for the same mixtures. The Prigogine-Flory-Patterson (PFP) theory has been applied to analyze of these systems. Furthermore, the apparent molar volumes, and apparent molar compressibility, of the components at infinite dilution have been calculated.
