Abstract: | The liquid-liquid equilibrium for the quaternary system of o-xylene(1)+water(2)+propionic acid(3)+1-butanol(4) was measured
at 298.15 K and atmospheric pressure. Binodal curves, tie-lines, a distribution curve, and a selectivity curve for the quaternary
system have been determined in order to investigate the effect of binary solvents, oxylene and 1-butanol, on extracting propionic
acid from aqueous solution. In addition, these experimental tie line data were also compared with the values predicted by
the UNIFAC model. In this study, the UNIFAC model was capable of predicting the compositions of this quaternary system within
an average RMSD of 1.13 mol%.
