摘要：
New experimental data on liquid-liquid equilibria (LLE), solubility and critical states in quaternary system propionic acid - 1-propanol - n-propyl propionate - water at 303.15 K and atmospheric pressure are presented. LLE was studied by Gas Chromatography (GC). Solubility and critical (plait) points were investigated by "cloud-point technique" method. Binodal curves and surfaces are presented in concentration tetrahedron. The critical curve is presented in 3d concentration space. A comparative analysis of the results obtained in the work with literature data is carried out. The experimental data are correlated by NRTL model. Standart deviation sigma for quaternary mixture does not exceed 0.344%. (C) 2020 Elsevier Ltd.
