IMIDAZOLIUM-BASED IONIC LIQUID COMPOUND MANUFACTURING METHOD FOR THE SAME AND METHOD FOR SEPARATING CARBON DIOXIDE USING THE SAME

摘要

The present invention relates to an imidazolium-based ionic liquid compound represented by structural formula 1, wherein the imidazolium-based ionic liquid compound according to the present invention functionalizes an amine to an imidazolium-based positive ion which is an ionic liquid, and by substituting amino acid into a negative ion of the ionic liquid, it is possible to improve acid gas absorption ability and lower viscosity of the ionic liquid by lengthening the residue of the imidazolium-based positive ion.
