Abstract

This work presents the high-pressure phase behavior of CO 2 with six ionic liquids: 1- n -butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF 6 ]), 1- n -octyl-3-methylimidazolium hexafluorophosphate ([C 8 -mim][PF 6 ]), 1- n -octyl-3-methylimidazolium tetrafluoroborate ([C 8 -mim][BF 4 ]), 1- n -butyl-3-methylimidazolium nitrate ([bmim][NO 3 ]), 1-ethyl-3-methylimidazolium ethyl sulfate ([emim][EtSO 4 ]), and N -butylpyridinium tetrafluoroborate ([ N -bupy][BF 4 ]). We explored the effect of systematically changing the anionic and cationic components of the ionic liquid on the CO 2 −ionic liquid phase behavior. For all of the ionic liquids tested, large quantities of CO 2 dissolved in the ionic liquid phase, but no appreciable amount of ionic liquid solubilized in the CO 2 phase. In addition, the liquid phase volume expansion with the introduction of even large amounts of CO 2 is negligible, in dramatic contrast to the large volume expansion observed for neutral organic liquids. Our results seek to elucidate the underlying physical mechanisms of this highly unusual phase behavior.

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.
