ABSTRACT

(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.
