N2 - The study of chemical equilibria for the acetic acid-n-butyl alcohol-n-butyl acetate-water system at 318.15 K and 101.3 kPa is presented. New experimental data are obtained for chemically equilibrium states in homogeneous and heterogeneous regions with the use of gas chromatography analysis. Critical states corresponding to chemically equilibrium regions are discussed. All results are displayed on concentration diagrams in 3D and 2D versions (using variables α). As a result of comparing the obtained results with the literature data, the corresponding conclusions were drawn. For the correlation of experimental data, the model NRTL was applied. The analysis and calculation of concentration and thermodynamic equilibrium constants have been carried out. The model UNIFAC was used to calculate the thermodynamic constant.
