In order to evaluate the NRTL parameters for methyl acetate(
1) + [EMIM][SCN](3) binary, we also employed the objective
function (15), but in this case requiring as a constraint the fulfillment
of LLE condition for experimentally determined mutual solubilities.
In addition, the value of methyl acetate activity in the
heterogeneous mixture as determined by HSGC-EC technique
was considered in the objective function (15) at the coexisting liquid
compositions.
