Tie-line data for aqueous mixtures of butyric acid with isobutyl acetate at various temperatures
Ghanadzadeh H, Asgharzadeh S, Dastmoozeh N, Shekarsaraee S
Experimental liquid-liquid equilibrium (LLE) data for the system of (water+butyric acid+iso-butyl acetate) were obtained at T=(298.2, 303.2, 308.2, and 313.2) K and atmospheric pressure. This ternary system exhibits type-1 behavior of LLE. The experimental tie-line data were correlated using the UNIQUAC and NRTL models. The reliability of the experimental tie-line data was determined by applying the Othmer.Tobias and Hand correlations. Distribution coefficients and separation factors were calculated over the immiscibility regions.
Keywords: Butyric Acid; LLE Data; Ternary Mixture; NRTL Model; UNIQUAC Model
