ABSTRACT

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, Vm E , deviations in the viscosity, centse, deviations in the refractive index, centsnD, and the deviations in the surface tension, centso, at these three temperatures. The calculated quantities of Vm E , centse, centsnD, and centso were fitted to the Redlich-Kister equation to estimate the binary interaction parameters.
