| Popis: | Tie-line data for water + ethanol + sec-butyl acetate (SBAC) and water + 2-propanol + SBAC systems were determined at T = (293.15, 298.15, 303.15, 308.15) K under 100 kPa. This measurement data were correlated by using modified and extended UNIQUAC solution models. Liquid–liquid phase diagrams at the four temperatures were drawn and compared. The Bachman equation was applied to verify the thermodynamic consistency of the experimental data. Distribution coefficients and separation factors were calculated from the tie-line data and evaluated the effectiveness of SBAC for the extraction of alcohols from aqueous solutions. |
