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 313.15k
Densities (rho), viscosities (eta), 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 313.15K and atmospheric pressure have been measured. From the experimental data, excess molar volume (V-E), deviations in speed of sound (u(D)), excess isentropic compressibilities (k(s)(E)), and viscosity deviations (Delta eta) 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 V-E and k(s)(E), over the entire range of mole fraction, exhibited positive deviations, while u(D) and Delta eta showed negative variations.
