Experiment and Correlation of Liquid–Liquid Equilibrium Data for Water + 2-Propanol + 1-Octanol or n-Propyl Acetate at 298.2, 308.2, and 318.2 K under 101.3 kPa

The basic liquid–liquid equilibrium data of two systems {water + 2-propanol (IPA) + 1-octanol/n-propyl acetate} were measured. The distribution coefficients of the 2-propanol and the separation factors of the systems were calculated to analyze the extraction ability of the two extractants that extract IPA from water. The correlation model Hand equation was used to fit the data. The value of the linear correlation coefficient R2 > 0.99 indicates...
