Abstract

An important area of green chemistry is the replacement of hazardous solvents in chemical processes. Supercritical carbon dioxide (scCO₂) and, more recently, ionic liquids have been the primary candidates for such green replacement solvents. While surfactants have been used extensively to broaden the range of applications for scCO₂, very few investigations have been reported concerning surfactants in ionic liquid solvent media. We present here an overview of the role of surfactants in scCO₂ and ionic liquids and illuminate the prospects of combining the solvent properties of these two environmental solvent systems.
