چکیده مقاله:
Experimental solubility and tie-line data for the ternary system of (water + phosphoric acid + amyl acetate) were measured at T =308.2 K and ambient pressure. Data for the binodal curve were determined by cloud-point titration method. The concentration of each phase was determined by acidimetric titration, the Karl–Fischer technique, and refractive index measurements. A type-1 LLE phase diagram was obtained for this ternary system [1]. The experimental values were regressed and acceptably correlated using the UNIQUAC and NRTL models. The reliability of the experimental data was determined through the Othmer–Tobias plot. Distribution coefficients and separation factors were evaluated over the immiscibility region.
