Deviation from ideal behavior in the liquid phase is considered using the Wilson model. Gas-phase dimerization of acetic acid is also taken into account. The dimerization equilibrium constant was taken from G. Venimadhavan, M. Malone, and M. Doherty, "Bifurcation Study of Kinetic Effects in Reactive Distillation," AIChE Journal, 45(3), 1999 pp. 546–556:

, where is the temperature in Kelvins.

The bubble-point and dew-point curves are represented in red and green, respectively. The equilibrium curve is show in blue.
