Synthesis and combined properties of novel fluorinated anionic surfactant

► The novel fluorinated anionic surfactant sodium p-perfluorononenyloxy benzene sulfonate (SPBS), which did not belong to perfluorooctane sulphonate, was successfully prepared by sulfonation of p-perfluorononenyl phenyl ether (PPE). ► PPE was synthesized from the intermediate perfluoro nonene and phenol as the staring reactants. ► SPBS has excellent surface activity and combined properties.
