ABSTRACT

The isobaric vapor-liquid equilibrium (VLE) data for the two binary systems of (methanol + dibutyl carbonate and n-butanol + dibutyl carbonate) were measured with a modified Rose equilibrium still under pressures of 40.0, 70.0, and 100.0 kPa in this work. The thermodynamic consistency tests of the experimental VLE data were performed according to the methods of the Herington area test and Van Ness point test. All of the experimental isobaric VLE data were well-correlated using nonrandom two-liquid (NRTL), Wilson, and Margules activity coefficient models. And the results showed that the average absolute deviations (AAD) of the vapor-phase mole fraction (Cy) between the calculated and the experimental values were less than 0.01 and the maximum absolute average deviations of the boiling temperature (AADT) was 0.13 K. Consequently, the calculation values showed good agreements with the experimental data measured for the two binary systems in this study.
