Abstract: The aim of this paper is to compare various types of objective functions for the treatment of the isothermal vapour-liquid (V-L) equilibrium data. The comparison is made for nine various x-y-P equilibrium data sets (exhibiting positive or negative deviations from ideal behaviour with and without azeotrope). From the results it is apparent that the objective function based on the maximum likelihood method offers the best results, the reproducibility of V-L equilibrium data has the Lest quality.
