| Ionic liquids have inherent properties that make them attractive for use as solvents in industrial processes. They have negligible vapor pressure, good thermal stability, and they have the ability to influence the rates and the endo/exo selectivities of organic reactions. In recent studies, ionic liquids have been used as solvents in various types of reactions because of their catalytic enhancements and potential for recycling. Ionic liquids have been found to affect the rate of the cycloaddition of carbon dioxide to propylene oxide, which generally occurs at low rates when carried out at room temperature. We have studied how varying amounts of cation-anion ratios of N-1-butylpyridinium cation (BP+) and chloroaluminate counterions impact the cycloaddition rate of carbon dioxide to propylene oxide. The molecular factors of ionic liquids that accelerate the rate of reaction have been identified and will be discussed for this important reaction in carbon dioxide chemical sequestration. |
