Densities, viscosities, and refractive indices of binary mixtures of anisole with benzene, methylbenzene, ethylbenzene, propylbenzene, and butylbenzene at (293.15 and 303.15) K

Density (rho), viscosity (eta), and refractive index (n(D)) data of the binary mixtures of anisole + benzene, + methylbenzene, + ethylbenzene, + propylbenzene, and + butylbenzene were measured over the whole composition range at (293.15 and 303.15) K and atmospheric pressure. The viscosity data were correlated by empirical and semiempirical equations. The refractive index data were compared with calculated values using different models based on mixing rules. The excess molar volumes (V-E) and viscosity deviations (Delta eta) were derived from the measurements. The V-E and Delta eta of binary mixtures were fitted to Redlich-Kister polynomial equation. The excess and deviation functions are negative and decrease with increasing side chain length of the parent benzene molecule in the following order: benzene > methylbenzene > ethylbenzene > propylbenzene > butylbenzene.
