The vast potential of carbon dioxide(CO2) as an environmentally benign, clean, abundant, and tunable solvent has been realized on a variety of fronts, including cleaning protocols in microelectronics and garment care industries, coatings, and polymer production and processing. To take advantages of CO2s benefits, however, it is often necessary to confront an important limitation, namely its low capacity for solubilzing many materials, including water and water-only-soluble material. Here, we report our recent finding on relatively non-toxic amino acid derivatives as a CO2-soluble surfactant that enable significant water uptake within a continuous CO2 phase. Also, studies on the development of CO2-soluble chelating agents to make CO2-insoluble metal ions soluble and then extractable into CO2 are described. |
