Liquid−Liquid Equilibria of Aqueous Biphasic Systems Containing Selected Imidazolium Ionic Liquids and Salts
Open accessAbstract
Liquid−liquid equilibrium data have been determined for imidazolium ionic liquid ([C 4 mim]Cl, [C 6 mim]Cl, [C 4 mim]Br, [C 6 mim]Br, [C 8 mim]Br, [C 10 mim]Br) + salt (KOH, K 2 HPO 4, K 2 CO 3, K 3 PO 4 ) aqueous biphasic systems at T = 298.15 K, and in part at T = (308.15 to 318.15) K. Factors affecting the binodal curves such as nature of ionic liquids and salts and temperature are also studied. The binodal curves are fitted to a three-parameter equation, and the tie-lines were described by the Othmer−Tobias and Bancroft equations. It is found that an increase in temperature caused no significant expansion of the two-phase area. However, the binodal curves became more close to the origin with an increase in alkyl chain length of the ionic liquids (ILs), and the ionic liquids with the Br - anion are easier to form two phases compared to those with the Cl - anion. These data are expected to be useful for the development and design of the extraction process using ILs based on aqueous biphasic systems.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
