The current paper presents experimental measurements of density, (rho), for binary liquid mixtures containing {dimethyl carbonate (DMC) + methanol, or + ethanol, or + 1-propanol)} over the whole composition range, over the temperature range from T= (288.15-308.15) K and pressure up to 40 MPa. The results were used to calculate the excess molar volumes (V-m(E)), which were correlated with a Redlich-Kister type polynomial equation. Other derived volumetric properties such as partial molar volumes ((V) over bar (i)) and apparent molar volumes (V-oi), isothermal compressibilities (kappa), thermal expansion coefficients (alpha) and internal pressures (pi) were also calculated. The V-m(E) values were used to test the applicability of the Prigogine-Flory-Patterson Theory (PFP Theory) and the Extended Real Associated Solution Model (ERAS Model). In order to complement the thermodynamic study and attempt to elucidate the main structural and interactional phenomena present in the systems studied, spectroscopic properties (FT-IR, H-1 NMR and C-13 NMR) have been investigated. The results suggest that for the {DMC + methanol} system, structural and chemical effects should be predominant over the physical effects, while physical interactions must prevail in the systems containing ethanol and 1-propanol.
