The excess molar volumes VE were determined from density, while the excess Gibbs free energy of activation G*Ewas calculated from viscosity deviation Delta eta. The excess molar volume (V E), viscosity deviation (Delta eta), and excess Gibbs energy of activation (G*E) were fitted to the Redlich-Kister polynomial equation to derive binary coefficients and estimate the standard deviations between the experimental data and calculation results. All mixtures showed positive V E values obviously caused by increased physical interactions between biodiesel and the organic solvents.en10.1134/S0036024408130189info:eu-repo/semantics/closedAccessArticle821322602268Q4WOS:000261182600018Q4
