Résumé: This work is a contribution to a research program concerning on the investigation of thermodynamic and thermophysical properties of binary mixtures containing compounds derived from biomass (2,5-DMF, MIBK ,…). The densities, sound velocities and refractive index were measured at four temperatures and atmospheric pressure for twelve binary systems. From these experimental data, excess molar volume, isentropic compressibility, excess isentropic compressibility, refractive index deviation; have been calculated over the entire composition range and at each temperature. Derived properties data have been correlated using the Redlich−Kister equation. The (T,P,x) data were obtained using an original static apparatus at different temperatures. The Experimental vapor pressures of pure components and binary mixtures have been adjusted by the iterative least squares method using the Antoine equation. The Barker method was used to determine the excess properties and activity coefficients of the deferent component. The experimental data obtained were used to estimate the interaction parameters using NRTL and UNIQUAC models
