Abstract

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. The obtained parameters made it possible to describe the vapor-liquid equilibrium in the acetic acid-acrylic acid system: to calculate the composition of the equilibrium phases, the activity coefficients of the solution components, the separation coefficient and to construct p-x isothermal boil diagrams.
