| Abstract: | (Liquid + liquid) equilibrium tie-lines were measured for one ternary system {x1H2O + x2(CH3)2CHOH + (1 ? x1 ? x2)CH3C(CH3)2OCH3} and one quaternary system {x1H2O + x2(CH3)2CHOH + x3CH3C(CH3)2OCH3 + (1 ? x1 ? x2 ? x3)(CH3)2CHOCH(CH3)2} at T = 298.15 K and P° = 101.3 kPa. The experimental (liquid + liquid) equilibrium results were satisfactorily correlated by modified and extended UNIQUAC models both with ternary and quaternary parameters in addition to binary ones. |
