U ovom radu raspravljeno je ponašanje trokomponentnih sustava voda (1) – octena kiselina (2) – organski ester (3) pri ravnoteži kapljevina-kapljevina i potencijalni čimbenici koji na nju mogu utjecati. Temeljem eksperimentalnih podataka (ravnotežnih sastava) preuzetih iz literature izračunati su interakcijski parametri za modele NRTL i UNIQUAC čija je konzistentnost testirana postupkom Marcille i suradnika. Oba modela na zadovoljavajući način opisuju ponašanje istraženih trokomponentnih sustava. This work discusses the behavior of water (1) – acetic acid (2) – organic ester (3) three-component systems at liquid-liquid equilibrium and potential factors that can affect it. Based on the experimental data (equilibrium compositions) taken from the literature, the interaction parameters for the NRTL and UNIQUAC models were calculated, and their consistency was tested by the procedure of Marcilla et al. Both models satisfactorily describe the behavior of the investigated three-component systems.
