Liquid−Liquid Equilibria for Mixtures of (Furfural + an Aromatic Hydrocarbon + an Alkane) at T = 298.15 K (original) (raw)

Liquid-liquid equilibrium results for mixtures of furfural + an aromatic hydrocarbon + an alkane at T) 298.15 K are reported, where an aromatic hydrocarbon is benzene or methylbenzene or 1,2dimethylbenzene or 1,3-dimethylbenzene or 1,4-dimethylbenzene and an alkane refers to n-hexane or n-dodecane or n-hexadecane. The data were measured using the titration method and show a large solubility gap for all mixtures studied. The selectivity values are large, indicating that furfural is capable of separating aromatic hydrocarbons from aliphatic hydrocarbons by solvent extraction. The data were correlated with the UNIQUAC equation, the NRTL equation, and three analytical equations.
