Abstract
Isobaric vapor–liquid equilibrium (VLE) data for the binary system of methyl myristate+methyl palmitate at 0.5, 1.0 and 1.4kPa 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.
