In this study, the kinetics data of extraction were measured at different temperatures (25, 40 and 55 ◦C) and using different mass fractions of biodiesel with anhydrous ethanol (0, 5 and 10%). To describe these extraction processes, first-order and second-order models as well as the mass transfer kinetic model (MTKM) were fitted to the experimental data. The parameters obtained for each model and the statistical results are presented in Table 1. The mass transfer model was truncated at the first term (n = 0). As shown in Table 1, this order used was enough to get a good description of the experimental data.
