【 摘 要 】

Ionic liquids are a new and exciting class of compound that have the potential to overcome many of the problems associated with current CO{sub 2}-capture techniques. Ionic liquids (ILs) are organic salts that are liquid in their pure state near ambient conditions. ILs are regarded as potentially environmentally-benign solvents due to their immeasurably low vapor pressure, which essentially eliminates the opportunity for solvent release to the atmosphere. The goal of this project is to obtain a fundamental understanding of the solubility of CO{sub 2} and other components present in flue gas in ILs, with the practical objective of tailoring the properties of the liquid to maximize the engineering properties for this process. Our plan is to do this through a combination of synthesis and experimental measurements, molecular simulation and applications development. This third quarterly technical report (Q2 2005) describes the results of our work on this project from 01/01/2005 through the end of the third quarter (03/31/05).
