摘要：
Tetradecane was used as back-extractant to extract the residual octane and nonane in the extraction phase after the extraction of butanol + octane + nonane mixture with ethanol aqueous solution. The liquid-liquid equilibrium (LLE) data of the quinary systems ethanol+butanol+octane or nonane+water+tetradecane and the six-component system ethanol+butanol+octane+nonane+water+tetradecane were obtained under 298.15K and atmospheric pressure. The accuracy of the LLE data was examined by the Othmer-Tobias equation with the linear correlation R2 ≥0.986 3. The LLE data of the quinary systems were regressed by the non-random two liquids (NRTL) model and related binary interaction parameters were obtained to predict the LLE data of the six-component system. The results show that the predicted values are in great agreement with experimental data, which indicates that the regressed parameters have high accuracy. © 2021, Editorial Board of "Journal of Chemical Engineering of Chinese Universities".
