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 (1) and a water/supercritical carbon dioxide microemulsion including the surfactant.
Claims9
A surfactant for stabilizing a water/supercritical carbon dioxide microemulsion, the surfactant comprising a compound of Formula (1):
- (where Rf is a C1-7 perfluoroalkyl group, and M is a hydrogen atom, an alkali metal, ammonium, a basic amino acid residue, an alkanolamine residue having a C2-3 hydroxyalkyl group, or an aliphatic alkanolammonium).
