The synthesis of double tail surfactants having crown ethers as polar heads was performed by reacting di-F-alkyl mercaptosuccinate on cyclic polyethylene glycol maleates. Surface tension and critical micelle concentration (CMC) were determined for these new surfactants. According to CMC values, the solubility in water is higher with perfluoroalkyl surfactants having a bigger loop size and shorter hydrophobic chains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
