Isentropic compressibility k s , excess isentropic compressibility k s E , excess molar volume V E , viscosity deviations ∆η, and speed of sound deviations u D for {chlorobenzene + 1-hexanol or 1-heptanol, or 1-octanol, or 1-nonanol, or 1-decanol} binary mixtures at temperatures ranging from (298.15 to 313.15) K and at atmospheric pressure were derived from experimental viscosity η, density F, and speed of sound u data. The calculated excess and deviation functions were further fitted to the polynomial relation to estimate the coefficients and standard errors. While the experimental viscosity data was compared with the predicted values obtained from empirical expressions, the speeds of sound data was analyzed in term of Schaaffs' collision factor theory and Jacobson's intermolecular free length theory of solutions. The effects of n-alkan-1-ol chain length as well as the temperature on the excess molar volume were studied.

Density (F), viscosity (η), 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 (∆η) were derived from the measurements. The V E and ∆η 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.
