Isobaric vapor–liquid equilibrium for binary system of methyl myristate + methyl palmitate at 0.5, 1.0 and 1.4 kPa

• Isobaric VLE data were reported for the binary systems at 0.5, 1.0 and 1.4 kPa.
• Thermodynamic consistency of the experimental data was checked both with the Wisniak consistency test and Van Ness test.
• The experimental VLE data were regressed with NRTL and Wilson models.
• The experimental VLE data were predicted by UNIFAC and Dortmund (modified UNIFAC) models.
• All the four models indicate a reasonable agreement between experimental and calculated data for the VLE data.

Isobaric vapor–liquid equilibrium (VLE) data for the binary system of methyl myristate + methyl palmitate at 0.5, 1.0 and 1.4 kPa were measured by a VLE modified Othmer still. The esters used in this paper are the major components of biodiesel. The experimental data in the vaccum conditions passed the Wisniak consistency test and point consistency test of Van Ness test, which ensure the reliability of experimental data. Furthermore, these VLE data were correlated with Nonrandom two-liquid (NRTL) activity coefficient model and Wilson model, and predicted by UNIFAC and Dortmund (modified UNIFAC) models. The results indicate that the calculated values of these four models agree well with the experimental data.
