摘要
Isobaric vapor–liquid equilibrium (VLE) data for 1-propanol + 1-(methoxymethoxy)-butane and 1-butanol + 1-(methoxymethoxy)-butane systems were measured at 101.3 kPa with a modified Rose still. The results indicated that two minimum temperature binary azeotropes were formed in two systems above. Thermodynamic consistency of the experimental data was confirmed by the Herington semi-empirical method. Saturated vapor pressure data for the pure component of 1-(methoxymethoxy)-butane used in the VLE calculations were measured. The experimental binary system equilibrium data were correlated by Van Laar, Wilson, and Non-Random Two Liquids (NRTL) activity coefficient models. The corresponding binary interaction parameters of the Van Laar, Wilson, and NRTL models were also obtained. By comparing the experimental value with the calculation values of the three models, the results showed that the Wilson and NRTL models used satisfactorily correlate the experimental results of two binary systems above.
