ABSTRACT

Isobaric vapor-liquid equilibrium (VLE) data for 1-butanol+methoxy (methoxymethoxy)methane (DMM2), and 1-butanol + 2,4,6,8-tetraoxanonaner (DMM3) systems were measured at 101.3 kPa with a modified Rose still. The experimental binary system equilibrium data was correlated by Wilson, Non-Random Two Liquids (NRTL), and Universal Quasi-Chemical (UNIQUAC) activity coefficient models. Our results show that the calculated data is consistent with the experimental data. And the corresponding binary interaction parameters of the Wilson, NRTL and UNIQUAC models were obtained. By comparing the experimental value with calculation values of three models, the average absolute deviation in boiling point and vapor-phase composition (delta-T/delta-y) were determined and two sets of average values were less than 0.28 K and 0.0126, respectively. We confirmed the thermodynamic consistency of the experimental data by the Herington semi-empirical method.
