Data 2009 2009-02-25 Liquid-Liquid Equilibria in Ternary Systems 2-Methylbutane + 2-Methyl-2-propanol + Water and Pentane + 2-Methyl-2-propanol + Water at 293.15 K The liquid-liquid equilibria in ternary systems 2-methylbutane + 2-methyl-2-propanol + water and pentane + 2-methyl-2-propanol + water were experimentally determined at 293.15 K by direct analytical methods and a titration method. The ternary data along with other thermodynamic data of binary subsystems previously published were utilized for a thermodynamic description of the systems. The original UNIQUAC model was combined with a ternary term. Binary parameters of the model were considered to be temperature dependent, and they were calculated employing the maximum likelihood method. Ternary parameters were evaluated using a nonderivative numerical procedure. 10.1021/je8004529 54 417-422 1 2-methylbutane C5H12 1 Commercial source 1 99.7 3 Stated by supplier 2 .01 1 Karl Fischer
