<P>PROBLEM TO BE SOLVED: To provide a surfactant for a microemulsion, in which high water dispersion capacity, water/supercritical carbon dioxide microemulsion-forming ability under the mild conditions, and rapid water solubilization speed can be achieved, and there is little load to the environment and ecology. <P>SOLUTION: The surfactant for stabilizing the water/supercritical carbon dioxide microemulsion includes a compound expressed by the following formula (1). In addition, the microemulsion is disclosed. In the formula, Rf denotes a 1C-7C perfluoroalkyl group, and M denotes a hydrogen atom, an alkali metal, ammonium, an alkanolamine residue having a basic amino acid residue or a 2C-3C hydroxyalkyl group, or an aliphatic alkanol ammonium. <P>COPYRIGHT: (C)2012,JPO&INPIT |
