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 hydrocarbon+monocarboxylic acid binary systems were measured. Hexane, 1-hexene, cyclohexane, and benzene were adopted for the hydrocarbons, and acetic acid and propionic acid for the monocarboxylic acids. The experimental data obtained in this work are found to be thermodynamically consistent. They are correlated by applying the NRTL model to liquid-phase activity coefficients and by assuming vapor-phase association of monocarboxylic acids.
