摘要: A novel branched fluorinated anion surfactant 4-(3,3,4,4,5,5,5-heptafluoro-2,2-bis-tri-fluoromethyl-pentyl)benzene lithium phosphonate was successfully synthesized via a four-step route using perfluoro-2-methyl-2-pentene as starting material. The surface activity investigated. result showed that the cmc value of in water is about 1.5x10(-2) mol/L at 298 K and tension aqueous solution 19.2 mN/m cmc.
