Solubility in the system acetic acid – n-amyl alcohol – n-amyl acetate – Water at 293.15 K, 303.15 K, 313.15 K and 323.15 K and atmospheric pressure

Abstract

Solubility of the quaternary system acetic acid – n-amyl alcohol – n-amyl acetate – water was investigated at 293.15 K, 303.15 K, 313.15 K, 323.15 K and atmospheric pressure. Binodal curves and binodal surfaces were determined using isothermal titration (cloud-point technique) and presented in composition simplices including 3D phase diagrams in composition tetrahedron. Binary mixtures were carried out by the gas chromatography method. Experimental data were predicted using UNIFAC model, and it was found that the calculating results of liquid–liquid equilibria (LLE) are in inconsistent agreement with the experimental data on solubility at all temperatures.
