ABSTRACT
(Liquid + liquid) equilibrium tie-lines were measured for one ternary system {x1H2O+x2(CH3)2CHOH + (1-x1-x2)CH3 C(CH3)2OCH3} and one quaternary system {x1H2O +x2(CH3)2CHOH + x3CH3C(CH3)2OCH3 + (1-x1-x2 -x3)(CH3)2 CHOCH(CH3)2} at T = 298.15 K and P0 = 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.
