Isobaric vapor-liquid equilibria for ternary mixtures : Saturated hydrocarbons, xylenes, and ethylbenzene with sulfolane at 101.325kPa
Isobaric vapor-liquid equilibria have been determined for the partially miscible systems octane tp-xylene + sulfolane, nonane + o-xylene + sulfolane, nonane + p-xylene + sulfolane, and nonane + ethylbenzene + sulfolane at 101.325 kPa. The data have been compared with those calculated by the UNIFAC-group-contribution model. The calculated vapor-phase compositions and activity coefficients have been compared with the experimental values.
