Vapor-liquid equilibria of binary and ternary mixtures of cyclohexane, 3-methyl-2-butanone, and octane at 101.3 kPa

摘要: Vapor−liquid equilibria were measured at 101.3 kPa for the three binary and one ternary mixtures of cyclohexane, 3-methyl-2-butanone, octane. The isobaric T−x−y data reported, including an azeotropic point mixture cyclohexane + 3-methyl-2-butanone. virial equation state truncated after second coefficient was used to calculate vapor-phase fugacity coefficients. Tsonopoulos correlation applied determine Various activity models Wilson, NRTL, UNIQUAC equations correlate experimental vapor−liquid equilibrium results. Optimally-fitted parameters obtained those paramters NRTL model employed predict equilibria. Satisfactory results presented prediction on mixtures.
