ABSTRACT

The experimental equilibrium tie-line compositions for the three quaternary mixtures of (water + ethanol + dimethyl carbonate + 2,2,4-trimethylpentane), (water + ethanol + dimethyl carbonate + n-heptane), and (water + dimethyl carbonate + n-heptane + toluene) and the five ternary mixtures of (water + ethanol + dimethyl carbonate), (water + dimethyl carbonate + n-heptane), (water + dimethyl carbonate + 2,2,4- trimethylpentane), (water + dimethyl carbonate + toluene), (water + n-heptane + toluene) have been measured at a temperature of 298.15 K and ambient pressure. The experimental ternary and quaternary (liquid + liquid) equilibrium data were correlated with the modified and extended UNIQUAC models including binary and multicomponent interaction parameters.
