Abstract

Isothermal vapour-liquid equilibria for 15 binary systems and 7 ternary systems containing monocarboxylic acid were measured. For the binary systems, water, ethanol, butanol, methyl ethyl ketone, ethyl acetate, ethyl propionate, butyl aldehyde, and dibutyl ether were adopted for the polar compounds and acetic acid and propionic acid for the monocarboxylic acids. For the ternary systems, formic acid, acetic acid, propionic acid, and butyric acid were adopted for the monocarboxylic acids and hexane, water, ethanol, methyl ethyl ketone, and ethyl acetate for the other compounds. The experimental data of the binary systems obtained in this work were correlated by applying the NRTL model to liquid-phase activity coefficients and by assuming vapour-phase association. Furthermore, the vapour-liquid equilibria of the ternary systems were predicted by using the interaction parameters determined for the constituent binary systems.
