abstract 
To explore the type of interaction and its behavior with temperature in the binary mixture (dimethyl carbonate + benzyl benzoate), the density (p) and speed of sound (u) are measured for the whole mole fraction range at various temperatures T = (308.15, 313.15 and 318.15) K and at atmospheric pressure. Sign with magnitude of computed excess molar volume (VErn) was examined and detailed analysis elucidated not only prevalence of strong molecular interactions between molecules in study but also its variation with temperature. Further, strong interactions are well supported by partial and their excess partial molar volume ((V) over bar (m),(V) over bar (E)(m)(V) over bar (E,infinity)(m)). Furthermore, relative association (RA), LennardJones repulsive power (n), excess isentropic compressibility (14), partial and their excess partial molar isentropic compressibility((K) over barm (K) over bar), excess values of isobaric thermal expansion coefficient (alpha(E)(P)), isentropic compressibility (u(E)), isothermal compressibility (KT(E)), intermolecular free length (Lf(E)), acoustic impedance (Z(E)), surface tension ((A, ultrasonic speed (Ks(E)) were evaluated and confirmed the conclusions made for V. By RedlichKister equation, coefficients with standard deviations are computed to excess parameters. lfim is correlated by PrigogineFloryPatterson (PFP) and Topology theories at 308.15 K. Extended Langmuir model is examined for influence of the bulk mole fraction on surface tension. At T= 308.15 K, different derivatives of thermodynamic potentials, densities through SoaveRedlichKwong (SRK)/PengRobinson (PR) cubic equation of states, excess chemical potential and theoretical speeds using semiempirical equations are evaluated. Using HartmannBalizar and Ballou nonlinear equations, cohesive energy (Delta A), van der Wall's constants (a, b), distance of closest approach (d) are estimated through Sehgal's equations at all temperatures.
