Abstract

To collect liquid-liquid equilibrium data for various types of quaternary systems having different numbers of immiscible binaries, this work reports experimental liquid-liquid equilibrium data for type 1 quaternary system isooctane (2, 2, 4-trimethylpentane) (1) -methanol (2) -benzene (3) -toluene (4) and type 2 quaternarysystem heptane (1) -methanol (2) -toluene (3) -octane (4) at 25°C. Solubility datafor the quaternary systems were obtained by using the cloud point method and experimental tie-line data were measured by gas chromatographic analysis of both phases. Further, the present tie-line data were correlated with good agreement using an improved Wilson equation previously proposed by the authors.
