Densities, Viscosities, and Ultrasonic Velocity Studies of Binary Mixtures of Chloroform with Pentan-1-ol, Hexan-1-ol, and Heptan-1-ol at (303.15 and 313.15) K

Abstract

Densities, viscosities, and ultrasonic velocities of binary mixtures of chloroform with pentan-1-ol, hexan-1-ol, and heptan-1-ol have been measured over the entire range of composition at (303.15 and 313.15) K and at atmospheric pressure. From the experimental values of density, viscosity, and ultrasonic velocity, the excess molar volumes (V E), deviations in viscosity (Δη), and excess isentropic compressibility (κsE) have been calculated. The excess molar volumes (V E) are positive for all the three binaries studied over the whole composition, the excess isentropic compressibilities (κsE) are also positive except for low mole fractions of chloroform, while deviations in viscosities (Δη) are negative for all the three binary mixtures. The excess molar volumes, deviations in viscosity, and excess isentropic compressibility have been fitted to the Redlich−Kister polynomial equation. McAllister's three-body interaction model has been used to correlate the kinematic viscosities of binary liquid mixtures with ...
