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[image omitted]), 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[image omitted], over the entire range of mole fraction, exhibited positive deviations, while uD and Δη showed negative variations.
