Densities, viscosities and ultrasonic velocity studies of binary mixtures of toluene with heptan-1-ol, octan-1-ol and decan-1-ol at 298.15 and 308.15 K

Abstract

Densities, viscosities and ultrasonic velocities of binary mixtures of toluene with heptan-1-ol, octan-1-ol and decan-1-ol have been measured over the entire range of composition at (298.15, and 308.15) K and at atmospheric pressure. From the experimental values of density, viscosity and ultrasonic velocity, the excess molar volumes ( V E), deviations in viscosity (Δ η) and deviations in isentropic compressibility (Δ κ s) have been calculated. The excess molar volumes, deviations in viscosity and deviations in isentropic compressibility have been fitted to the Redlich–Kister polynomial equation.
