ABSTRACT

Densities and speeds of sound of ternary o-chlorotoluene (1) + tetrahydropyran (2) + benzene or toluene or o-xylene (3) mixtures and their sub-binaries o-chlorotoluene (1) + toluene or o-xylene (2) at (298.15, 303.15, and 308.15) K have been measured, and of tetrahydropyran (1) + benzene or toluene or o-xylene (2) mixtures at (298.15 and 303.15) K and 0.1 MPa. Excess molar volumes, V123E and VE, and excess isentropic compressibilities, (?SE)123 and ?SE, have been computed from experimental data. The V123E for o-chlorotoluene (1) + tetrahydropyran (2) + o-xylene (3) and (?SE)123 for o-chlorotoluene (1) + tetrahydropyran (2) + benzene or toluene or o-xylene (3) are negative over the entire mole fraction of 1 and 2. However, the sign and magnitude of V123E for o-chlorotoluene (1) + tetrahydropyran (2) + benzene or toluene (3) mixtures are dictated by the relative proportion of the constituents. The excess functions have been analyzed in terms of Graph theory, Prigogine Flory Patterson theory, and Sanchez and Lacombe s theories.
