Abstract: Isoplethic VLE data for the systems benzene-hexane at 9 different compositions in the
temperature range from 298K to 331K, chloroform-benzene at 11 different compositions in the
temperature range from 308K to 350K and chloroform-hexane at 9 different compositions in
the temperature range from 311K to 337K were determined by using an inclined ebulliometer
with a pump-like stirrer. Isothermal and isobaric VLE were calculated from the isoplethic
results with a extended UNIQUAC equation and these data agree well with the literature
data.

Key words: vapor-liquid equilibrium, ebulliometer, quasi-static method
