Abstract
For the first time symmetric models are presented for non-stoichiometric six-parameter models and comparative analysis has been carried out with empirical ternary symmetric and asymmetric models with the Redlich–Kister model taken as a basis. For asymmetric models on the basis of the component structuredness criteria, a simple quantitative mode is proposed for selecting the asymmetric component. On the basis of Chou’s method a new mode of computation has been proposed with the help of non-stoichiometric models. Calculations have been performed with the excess molar volumes and molar enthalpies dependence using ethanol or 1-butanol + triethylamine + n-hexane and 1-butanol + tri-n-butylamine (or tri-n-octylamine) + n-hexane mixtures as examples.
