  • Switchable Anionic Surfactants and Methods of Making and Using Same
    Publication number: 20110124745
    Abstract: Reversibly switchable negatively charged surfactants are provided. The anionic surfactant is formed in aqueous solution by providing an absence of CO2 and is converted to a non-surfactant neutral state through exposure to CO2. The anionic switchable surfactants are useful to stabilize emulsions. In the neutral state they are useful to separate immiscible liquids. The surfactants find uses in polymerization, the oil industry, remediation of oil-contaminated soil and recapture of oil contaminant, and formation of solid particles such as plastics and nanoparticles.
