Reversibly switchable negatively charged surfactants are provided. The anionic surfactant is formed in aqueous solution by providing an absence of CO
2
and is converted to a non-surfactant neutral state through exposure to CO
2
. 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.
提供可逆转开关的负电荷表面活性剂。通过提供无CO2的水溶液形成阴离子表面活性剂,并通过暴露于CO2下转化为非表面活性剂中性状态。可切换的阴离子表面活性剂有助于稳定乳液。在中性状态下,它们有助于分离不相溶的液体。表面活性剂在聚合物化学、石油工业、油污染土壤修复和油污染物的回收以及塑料和纳米颗粒的形成中发挥作用。
