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 cation which is an ionic liquid, and the amino acid is ionic. By substituting with the anion of the liquid, the acid gas absorption ability can be improved at atmospheric pressure, and the residue of the imidazolium-based cation can be lengthened to lower the viscosity of the ionic liquid.
