Ternary (liquid + liquid) equilibria for the extraction of ethanol, or 2-propanol from aqueous solutions with 1,1′-oxybis(butane) at different temperatures
چکیده انگلیسی


• LLE data of [water + ethanol or 2-propanol + 1,1′-oxybis(butane)] were measured at four temperatures.
• Tie-line data were correlated by using the extended and modified UNIQUAC models.
• The temperature influence on liquid-phase regions was analyzed.
• The ability of DBE to extract ethanol or 2-propanol from aqueous solutions was discussed.

(Liquid + liquid) equilibrium data for the ternary systems of {water + ethanol + 1,1′-oxybis(butane)} and {water + 2-propanol + 1,1′-oxybis(butane)} at T = (293.15, 298.15, 303.15, 308.15) K have been measured under atmospheric pressure. The experimental results were correlated by using the modified and extended UNIQUAC models. Distribution coefficients and separation factors of ethanol and 2-propanol were calculated and discussed in detail. The temperature influence on liquid-phase regions was analysed.
