volatile component. The experiments were carried out at compositions
covering various parts of the ternary composition space. The
aim was to gather ample and representative ternary data that
could be subsequently used (i) to test efficiently estimation of ternary
behavior from binary data only and (ii) to possibly improve
the description of ternary behavior using ternary parameters fitted
to the ternary data. Results of the corresponding calculations with
the NRTL equation, which proved to be the most suitable model to
fit experimental data for binary subsystems, are summarized in Table
12. As seen from this table, when using the binary data only,
the methyl acetate/methanol separation factor in the ternary systems
with ILs is predicted very decently, the overall RMSD in
lna12 being around 0.05, i.e. 5% in a12.
