An Anton Paar vibrating tube densimeter HPM DMA calibrated with an uncertainty of ±0.7 kg·m-3 has been used for accurate measurements of liquid densities of waste cooking oil biodiesel (WCOB) and 1-butanol as pure fluids and binary liquid mixtures The densities measurements were performed at temperatures (298.15 K to 393.15 K) and pressures (0.1 MPa to 140 MPa) and showing an absolute deviation of less than 0.007 g/cm-3 compared to the literature data. Using these new exptl. data (908 points), excess molar volumes VE, isobaric thermal expansivity, αp, and isothermal compressibility, κT, have been calculated The Tait and PC-SAFT equations correlate successfully the densities with a small absolute average deviation (AAD), the PC-SAFT model performs very well in all concentration range with a global absolute average deviation (AAD) of 0.325% and for Tait equation a global absolute average deviation of 0.086% for each concentration PC-SAFT equation correlates satisfactorily the d. and shows that it can explain the same interactions between fluid mols. contrary to the Tait equation. Excess volumes values were calculated from the exptl. data and show a pos. parabolic shape in all composition range almost sym. in the fraction molar 0.5. Furthermore, VE values were fitted to the Redlich-Kister equation and showed satisfactory correlation with very small standard deviation values with a global of 4.23·10-5 cm3·mol-1.
