“…Cano-Gómez et al have investigated the same sample WCOB + 2-butanol, and the absolute deviation between our experimental density data and those calculated using the Tait equation is lower than the corresponding density uncertainty with AAD = 0.09%, whereas the AAD calculated for the Cano-Gómez et al’s data was 0.27%. The absolute deviations calculated for biodiesel + 1-butanol and biodiesel + isobutyl alcohol by the same authors and for biodiesel + n -butanol by Geacai et al are 0.37, 0.36, and 0.71%, respectively.…”

“…Consequently, the density of the mixture decreases linearly with the WCOB volumetric fraction. Relative deviations between the experimental density data obtained in this work and those obtained by Tait correlation ( □ ) and from the literature: biodiesel + 1-butanol, (*) [38]; biodiesel (1) + isobutyl alcohol, (×) [38]; biodiesel + 2-butanol, (△) [38]; and biodiesel + n-butanol, (+) [37] 4.

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 methyl esters (FAME) that compose them. The main objective of the present work is to investigate the influence of 2-butanol addition on the waste cooking oil biodiesel (WCOB), for this fact, the new experimental density data (952 points) of WCOB + 2-butanol binary mixtures over a wide range of composition [seven compositions; 0 ≤ (WCOB) mole fraction x ≤ 1] between 0.1 and 140 MPa and 298.15 and 393.15 K are presented. The experimental data were correlated using Tait and perturbed chain-statistical associating fluid theory (PC-SAFT) equations of state (EoS), to our knowledge, this is the first time that density measurements for the WCOB + 2-butanol mixture are correlated using the famous PC-SAFT EoS. The Tait equation predicts successfully the density with a global absolute average deviation (AAD) of 0.089%, while the PC-SAFT model correlates well the density with a very small global AAD of 0.223% in each composition. Furthermore, contrary to the Tait equation, the PC-SAFT model can explain some interactions between fluid molecules. From the experimental data, the excess volumes V E have been calculated and fitted using the Redlich–Kister equation with a very small global standard deviation of 7.49 × 10–5 cm3 mol–1, and V E show a positive and symmetric parabolic shape in all composition ranges. Finally, the isobaric thermal expansivity, α p , and the isothermal compressibility, κT, have been derived from the Tait equation and their observed trend was as expected.

Densities and Viscosities for Binary Liquid Mixtures of Biodiesel + 1-Pentanol, 2-Pentanol, or 2-Methyl-1-Butanol from (288.15 to 338.15) K at 0.1 MPa

This work presents experimentally determined densities and viscosities of biodiesel blended with 1-pentanol, 2-pentanol, and 2-methyl-1-butanol between 288.15 and 338.15 K at 0.1 MPa. The densities are measured using a vibrating tube densimeter, and the kinematic viscosities, using a glass capillary viscometer. The measured density and viscosity of the pure components agree with values reported in the literature within average absolute percentage deviations of 0.04 and 0.83%, respectively. The excess molar volumes and viscosity deviations show positive and negative deviations from ideality, respectively. The Redlich−Kister equation is used to represent the composition behavior of the excess molar volumes and viscosity deviations. The experimental kinematic viscosities have a minimum value over a composition range of 50−90% alcohol by weight. The McAllister equation correlates the kinematic viscosity within an average absolute percentage deviation of 1.77%, while the Nava-Ri ́os equation correlates the kinematic viscosity within 0.88%.
