APPLICATION OF WILSON'S MODEL FOR DESCRIPTION OF PHASE EQUILIBRIUM OF VAPOR LIQUID FOR AZEOTROPIC SYSTEM ACETIC ACID – ACRYLIC ACID

Based on data on the composition of azeotropic solutions for the acetic acid - acrylic acid system, the parameters of the semi-empirical Wilson model for temperatures 320, 330, 340, 350 K were calculated using the mathematical software package Mathcad 14 by iterations.
