“…The mixture version of the TM EOS which was already developed by Yousefi et al , is given by where ρ is the total molecular number density, P is the pressure, x i and x j are mole fractions,and the double summation runs over all components. The interaction parameters B ij , α ij and b ij for i ≠ j correspond to a hypothetical single substance whose molecules interact according to a pairwise ij potential.…”

Densities and speeds of sound for the pure as well as binary mixtures of 1,2-butanediol and benzyl alcohol, 2-phenylethanol, 2-butanol, and 1,3-butanediol were measured over the 0 to 1 composition range and at six different temperatures between 298.150 K and 323.150 K with an interval of 5 K and at atmospheric pressure using a vibrating tube densimeter.The experimental values were used to calculate excess molar volume, V m E , excess isentropic compressibility, K S E , excess thermal expansion coefficient, α p E , infinite partial molar volumes, V̅ i ∞ and excess partial molar volumes at infinite dilution, V̅ i E,∞ . The sign and magnitude of mixing quantities have been used to discuss the nature and strength of molecular interactions in binary mixtures. The calculated excess values and deviation quantities were fitted to the Redlich−Kister polynomials equation. Furthermore, it has been checked how the calculated values of densities and excess molar volumes using the Tao−Mason equation of state compare with the experimental ones.

Densities and speeds of sound for five binary mixtures of benzylalcohol with 1,3-propandiol, 1-propanol, 2propanol, 1,2-propandiol and phenylethnol were measured over the entire range of composition and at five temperatures from 298.15K to 323.15K at 5K interval and atmospheric pressure using a vibrating u-tube densimeter (DSA 5000). Besides, the densities for pure compounds in the above-mentioned temperature range were measured. The experimental densities were used to calculate the excess molar volumes, isentropic compressibility changes, the excess thermal expansion coefficients, and the excess partial molar volumes at infinite dilution, The results have been used to discuss the nature and strength of intermolecular interactions in these mixtures. The calculated excess and deviations quantities are correlated with the third-order Redlich-Kister equation. As a final work we modeled the experiment results by using TM and PR EOSs. This is clear that the results with TM EOS are more acceptable than PR EOS. TM and PR EOS can successfully predict density and excess molar volume. And are unable to predict speed of sound.
