Abstract
A flow-type apparatus was constructed to measure isothermal vapor-liquid equilibria. The reliability of this experimental method was confirmed by comparing the data obtained with literature values. Isothermal vapor-liquid equilibria for the five monocarboxylic acid + monocarboxylic acid binary systems (formic acid + acetic acid, formic acid + propionic acid, acetic acid + propionic acid, acetic acid + butyric acid, and propionic acid + butyric acid) were measured. The experimental data obtained in this work were correlated by applying the NRTL model to liquid-phase activity coefficients and by assuming vapor-phase association between monocarboxylic acids.
