vapor-liquid equilibrium of allyl alcohol-water-acid acetic

vapor-liquid equilibrium of allyl alcohol-water-acid acetic

vapor-liquid equilibrium of allyl alcohol-water-acid acetic

Is about  acetoxylation of propylene in order to obtain allyl alcohol.
In the last distillation column of this plant is distillating a mixture of acetic acid, allyl
alcohol and water. The head product is allyl alcohol-water azeotrope and the sump
product is a mixture of acid acetic and water. In order to design this distillation
column I need the vapor-liquid equilibrium of the azeotrope and that acid-water mixture.
Should I calculate that equilibrium by suming the vapor pressures for both the azeptrope and  the mixture separately???
