Abstract: Equilibrium P-x data were measured at a temperature of 69.7°C for the mixtures hexane-cyclohexane, hexane-benzene-cyclohexane, hexane-cyclohexane-N-methylpyrrolidone, and hexane-benzene-cyclohexane-N-methylpyrrolidone. These equilibrium data along with data of other previously published systems were used in the assessment of the suitability of the Wilson equation for the prediction of vapour-liquid equilibrium for multicomponent mixtures employed in the extractive distillation.
