چکیده انگلیسی
Isobaric vapor-liquid equilibria for the binary mixtures of tert-butanol (TBA)Â +Â 2-ethyl-1-hexanol and n-butanol (NBA)Â +Â 2-ethyl-1-hexanol were experimentally investigated at atmospheric pressure in the temperature range of 353.2-458.2Â K. The raw experimental data were correlated using the UNIQUAC and NRTL models and used to estimate the interaction parameters between each pair of components in the systems. The experimental activity coefficients were obtained using the gas chromatographic method and compared with the calculated data obtained from these equilibrium models. The results show that UNIQUAC model gives better correlation than NRTL for these binary systems. The liquid-liquid extraction of TBA from aqueous solution using 2-ethyl-1-hexanol was demonstrated by simulation and the variation of separation factor of TBA at several temperatures was reported.
