Isobaric vapor-liquid equilibrium (VLE) data were measured at p = 1.01325 bar for the mixtures of ferrocene in ethanol, toluene, hexane, and 2,2,4-trimethylpentane ( isooctane). A dynamical equilibrium apparatus has been used to establish the equilibrium between the phases. The spectrophotometric method has been used to measure the compositions of vapor and liquid phases. Ferrocene is only weakly soluble in these solvents. The experimental binary data were correlated with the NRTL and UNIQUAC models, and the parameters were determined.
