Popis: In this work, experimental liquid–liquid equilibrium data for three pseudoternary systems containing {refined sunflower seed oil + aldehyde + anhydrous ethanol} were determined at a temperature T of 298.15 K with u(T) = 0.05 K and atmospheric pressure. Binodal curves and tie line compositions are reported for n-hexanal, 2-nonenal, or 2,4-decadienal as solutes. The nonrandom two-liquid1 and universal quasichemical2 models satisfactorily correlated experimental tie line data. Othmer–Tobias3 and Hand4 methods attested the quality of experimental data. Further, the predictive capabilities of four versions5−9 of the UNIFAC10 method were analyzed.
