摘要：
The solubility of Dynol-604 (a surfactant) in supercritical (SC) CO2 and the phase behavior of the CO2/water/Dynol-604 system were studied at different temperatures and pressures. The results showed that the solubility of the surfactant in SC CO2 is high and one-phase water-in-CO2 microemulsions could be formed although Dynol-604 is a nonfluorous, and nonsiloxane nonionic surfactant. The solvatochromic probe studies and the UV spectrum of lysozyme in the supercritical CO2/water/Dynol-604 system further proved the existence of a water domain in the supercritical CO2 microemulsions.
