![عکس صفحه اول مقاله: Extraction of propylbenzene or butylbenzene from dodecane using 4-methyl-N-butylpyridinium tetrafluoroborate, [mebupy][BF4], as an ionic liquid at different temperatures Extraction of propylbenzene or butylbenzene from dodecane using 4-methyl-N-butylpyridinium tetrafluoroborate, [mebupy][BF4], as an ionic liquid at different temperatures](/preview/png/216391.png)
Equilibrium tie line data have been determined for the two ternary liquid systems, namely {dodecane + propylbenzene + [mebupy][BF4]} and {dodecane + butylbenzene + [mebupy][BF4]} at temperatures (313, 323, and 333) K and atmospheric pressure. The effects of temperature and solvent to feed ratio upon solubility, selectivity, and distribution coefficient were investigated experimentally. The reliability of the experimental data was tested using the Othmer–Tobias correlation. The experimental results were regressed to estimate the interaction parameters between each of the three pairs of components for the UNIQUAC and the NRTL models as a function of temperature. In addition, the LLE data were also correlated with the UNIQUAC and NRTL models in a satisfactory manner.
► (Mebupy)(BF4) was evaluated for the separation of aromatics and dodecane.
► Reliability of the experimental data was ascertained by Othmer–Tobias correlation.
► Effect of temperature on selectivity and distribution coefficient were investigated.
► UNIQUAC and the NRTL models satisfactorily correlate the experimental data.
