ABSTRACT

In the present study, we reported the densities and excess molar volumes for the pure organic solvent mixtures such as {toluene (x1)+acetic acid (x2)}, {cyclohexane (x1)+acetic acid (x2)}, {toluene (x1)+1-hexanol (x2)}, {toluene (x1)+2-octanol (x2) } and {n-heptane (x1)+1-hexanol (x2) } at temperature range from (288.15 to 343.15) K and at a pressure of 0.1MPa. Excess molar volumes for these binary mixtures were calculated from the experimental density data and fitted to the Redlich-Kister polynomial equation to check the accuracy of experimental data. In addition, the interactions between the unlike molecules in the mixtures were confirmed by using the experimental results. We have also study the effect of temperature on molecular interactions between the molecules in the mixtures.
