Biodiesels will become the most popular alternative energy resource to fossil diesels; they can be used alone or blended with an oxygenated additive in any proportion. The properties of biodiesels strongly depend on the type of the fatty acid Me esters (FAME) that compose them. The main objective of the present work is to study the influence of 2-butanol addition on the waste cooking oil biodiesel (WCOB), for this fact, the new exptl. d. data (952 points) of WCOB + 2-butanol binary mixtures over a wide range [seven compositions; 0 ≤ (WCOB) mole fraction x ≤ 1] between 0.1 and 140 MPa and 298.15 and 393.15 K are presented. The exptl. data were correlated using Tait and perturbed chain-statistical associating fluid theory (PC-SAFT) equations of state (EoS), to the knowledge, this is the 1st time that d. measurements for the WCOB + 2-butanol mixture are correlated using the famous PC-SAFT EoS. The Tait equation predicts successfully the d. with a global absolute average deviation (AAD) of 0.089%, while the PC-SAFT model correlates well the d. with a very small global AAD of 0.223% in each composition Also, contrary to the Tait equation, the PC-SAFT model can explain some interactions between fluid mols. From the exptl. data, the excess volumes VE were calculated and fitted using the Redlich-Kister equation with a very small global standard deviation of 7.49 × 10-5 cm3/mol, and VE show a pos. and sym. parabolic shape in all composition ranges. Finally, the isobaric thermal expansivity, αp, and the isothermal compressibility, κT, were derived from the Tait equation and their observed trend was as expected.
