PHYSICOCHEMICAL PROPERTIES FOR BINARY MIXTURES OF ANISOLE WITH 1-HEXANOL, 1-HEPTANOL, 1-OCTANOL, 1-NONANOL, AND 1-DECANOL AT 298.15, 303.15, 308.15, AND 313.15 K

Abstract

Densities (ρ), viscosities (η), and speeds of sound (u) of binary mixtures of anisole with 1-hexanol, 1-heptanol, 1-octanol, 1-nonanol, and 1-decanol over the entire range of mole fraction and at temperatures 298.15, 303.15, 308.15, and 313.15 K and atmospheric pressure have been measured. From the experimental data, excess molar volume (VE), deviations in speed of sound (uD), excess isentropic compressibilities (k), and viscosity deviations (Δη) have been calculated and fitted to the Redlich-Kister type polynomial equation. The viscosity data were correlated with semi-empirical equations. The speeds of sound have been analyzed in terms of collision factor theory (CFT) and free length theory (FLT). The behavior of VE and k, over the entire range of mole fraction, exhibited positive deviations, while uD and Δη showed negative variations.
