ABSTRACT

Isentropic compressibility ks, excess isentropic compressibility ks E, excess molar volume V E, viscosity deviations centse, and speed of sound deviations uD 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 e, 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.
