Fig. (2) Ternary diagrams for ternary methanol + soybean oil + ionic liquid at atmospheric pressure (compositions are given in mole fractions). Ionic liquid stands for [C4mim][SCN] (a), [C4mim][NTf2] (b), [C4mim][DCA] (c), [C4mim][PF6] (d), [C4mim][HSO4] (e), [C10mim][NTf2] (f), [ALIQUAT][NTf2] (g), and [ALIQUAT][Cl] (h). The full lines and filled circles correspond to data at 298 K, while dashed lines and empty circles correspond to data at 343 K.
