N2 - We report isothermal volumetric properties for two binary systems constituted by 2,5-dimethylfuran (x) + a linear alkane (1 − x); octane and dodecane are the representative alkanes. Compressed liquid densities were obtained via oscillating period measurements in two commercial vibrating U-shaped tube densimeters. The experiments were performed within the pressure and temperature intervals from 0.1 MPa to 70 MPa and from 293 K to 393 K, respectively. Properties for these binary systems were measured at x = (0.1154, 0.2999, 0.4967, 0.6962, 0.8924) for 2,5-dimethylfuran + octane mixtures; whereas, compositions measured for 2,5-dimethylfuran + dodecane mixtures were x = (0.1995, 0.4067, 0.4972, 0.6053, 0.8045). Experimental density data were correlated by using the Tammann-Tait equation. Thermodynamic derived properties were calculated from the same equation, and their dependence on pressure, temperature and composition was discussed. These properties were isobaric thermal expansivity, isothermal compressibility, thermal pressure coefficient, internal pressure and mixing molar volume.
