Synthesis and Surface-Active Properties of F-Alkylated Polar Loops

摘要

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.
