Sažetak

Liquid-liquid phase equilibria (LLE) in the systems H2O – phenol – 2-butanone at 25 °C and H2O – phenol – 2-propanol at 25 °C were experimentally determined with a combination of turbidimetric titration and refractometry methods. UNIFAC model was found qualitatively suitable for prediction of LLE in both systems. NRTL and UNIQUAC model parameters were determined as well. The correlation was found qualitative for the system with 2-butanone and larger deviations from experimental data were found in the system with 2-propanol.
