Liquid-liquid Equilibrium Data For The Pseudoternary Model System Of Refined Sunflower Seed Oil Plus (n-hexanal, Or 2-nonenal, Or 2,4-decadienal) Plus Anhydrous Ethanol At 298.15 K

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)In this work, experimental liquidliquid 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-liquid(1) and universal quasichemical(2) models satisfactorily correlated experimental tie line data. OthmerTobias(3) and Hand(4) methods attested the quality of experimental data. Further, the predictive capabilities of four versions(5-9) of the UNIFAC(10) method were analyzed.61930693076CNPq [304303/2013-5]FAPESP [2013/11868-1, 2013/12735-5]Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP
