摘要：
Excess molar volumes, V-m(E), excess molar isentropic compressibilities, K-S, m(E), and deviations of the speeds of sound, u(D), from their ideal values u(id) in an ideal mixture for binary mixtures of 1-octanol, C8H17OH, with hexadecane, C16H34, and squalane (2,6,10,15,19,23-hexamethyltetracosane), C30H62, at T =(298.15, 303.15, 308.15) K and at atmospheric pressure were derived from experimental density, rho, and speed-of-sound data, u. Viscosity measurements were also carried out for the same mixtures. The Prigogine-Flory-Patterson (PFP) theory has been applied to analyze V-m(E) of these systems. Furthermore, the apparent molar volumes, (V) over bar (0)(phi,i) and apparent molar compressibility, (K) over bar (0)(phi,i) of the components at infinite dilution have been calculated.
