Abstract: On the basis of four ternary systems hydrocarbon—hydrocarbon—polar solvent, different types of objective function are appreciated from the view-point of calculation of parameters of universal ternary correction of the molar excess Gibbs energy by which the NRTL equation is extended. The quality of prediction of equilibrium data is judged in the form of residues of mole fractions and distribution coefficients.
