Densities, viscosities, refractive indexes, and surface tensions for binary mixtures of 2-propanol plus benzyl alcohol, plus 2-phenylethanol and benzyl alcohol plus 2-phenylethanol at T equals (298.15, 308.15, and 318.15) K
Densities, viscosities, refractive indexes, and surface tensions for three binary systems (2-propanol + benzyl alcohol, 2-propanol + 2-phenylethanol, and benzyl alcohol + 2-phenylethanol) were measured at T = (298.15, 308.15, and 318.15) K over the whole composition range at atmospheric pressure. Densities were determined using a vibrating-tube density meter. Viscosities were measured with an automatic Ubbelholde capillary viscometer. Refractive indexes were measured using a digital Abbe-type refractometer. Surface tensions were determined by the Wilhelmy-plate method. These results are used to calculate excess molar volumes, V(m)(E), deviations in the viscosity, Delta eta, deviations in the refractive index, Delta n(D), and the deviations in the surface tension, Delta sigma, at these three temperatures. The calculated quantities of V(m)(E), Delta eta, Delta n(D), and Delta sigma were fitted to the Redlich-Kister equation to estimate the binary interaction parameters.
