    Abstract

    The infinite dilution activity coefficients for benzene, toluene, ethylbenzene, n-heptane, n-octane, n-nonane, and n-decane in triethylene glycol and tetraethylene glycol were experimentally measured by gas chromatography at (50 to 130) °C. The experimental data were correlated with the modified UNIFAC (Dortmund) method, and the group interaction parameters were obtained. The experimental data were compared with the calculated results, and a good agreement between experimental data and calculated values was obtained.
