Abstract
The present invention provides a novel piperazinium trifluoroacetate compound prepared by reacting piperazine with trifluoroacetic acid and a carbon dioxide absorbent prepared by dissolving the compound in an ionic liquid or organic solvent. According to the present invention, the carbon dioxide absorbent has excellent carbon dioxide absorption capacity and low solvent loss, and the energy consumption required for the carbon dioxide absorption and desorption is significantly reduced.
