Abstract
A surfactant for water/supercritical carbon dioxide microemulsions that can achieve high water dispersion ability, water/supercritical carbon dioxide microemulsion forming ability under a moderate condition, and high water solubilization rate and that reduces burden on the environment and ecosystem. Provided are a surfactant for stabilizing a water/supercritical carbon dioxide microemulsion including a compound of Formula (I) and a water/supercritical carbon dioxide microemulsion including the surfactant. The compound of Formula (I) has the structure:
Claims5
A water/supercritical carbon dioxide microemulsion comprising a surfactant, wherein the surfactant has a concentration of 10−10% by mol to 102% by mol based on a molar amount of the supercritical carbon dioxide and the surfactant comprises a compound of Formula(1):
- where Rf is a C1-7 perfluoroalkyl group, M is a hydrogen atom, an alkali metal, ammonium, a basic amino acid residue, an alkanolamine residue having a C2-3 hydroxyalklyl group, or aliphatic alkanolammonium.
