Binary Vapor-Liquid Equilibria at Elevated Pressures

Abstract

Vapor-liquid equilibrium data for the binary systems methyl acetate-methanol and methyl acetate-water were determined at 5.78 atm, 8.66 atm, and 11.57 atm under nitrogen pressure. These data were correlated by Wilson s and Scatchard s equations. In both correlations the average deviations in the predicted results were fairly small for the system methyl acetate-methanol but not for the system methyl acetate-water. The effect of pressure on the azeotrope formed was represented by two sets of empirical equations.
