Beschreibung
Zusammenfassung:	The present disclosure relates to ionic liquids for carbon dioxide absorption. The present disclosure relates to an ionic liquid comprising a cation derived from nitrogen containing heterocyclic compound and an anion. The nitrogen containing heterocyclic compound is substituted with a dihydroxyalkyl group selected from 1,2-dihydroxyalkyl, and 1,3-dihydroxyalkyl. The present disclosure also provides a process for the preparation of the ionic liquid. The ionic liquid disclosed in the present disclosure has carbon dioxide absorption capacity in the range of 0.05 mole to 2.0 mole of carbon dioxide per mole of the ionic liquid. La présente invention concerne des liquides ioniques pour l'absorption de dioxyde de carbone. La présente invention concerne un liquide ionique comprenant un cation obtenu à partir de composé hétérocyclique contenant de l'azote, et un anion. Le composé hétérocyclique contenant de l'azote est substitué par un groupe dihydroxyalkyle choisi parmi 1,2-dihydroxyalkyle et 1,3-dihydroxyalkyle. La présente invention concerne également un procédé pour la préparation du liquide ionique. Le liquide ionique selon la présente invention a une capacité d'absorption de dioxyde de carbone dans la plage de 0,05 mole à 2,0 mole de dioxyde de carbone par mole du liquide ionique.
