Abstract: A cationic fluorinated surfactant,C8F17(CH2)2CONH(CH2)3N+(CH3)3I- (FTAI),was synthesized with perfluorooctyliodoethane (C8F17CH2CH2I) as starting material through a series of reactions,including Grignard reaction,acylchlorination,amidation and quaterization.Structure of the FTAI was characterized by IR,1HNMR and 19FNMR.The surface tension,the contact angle on paraffin wax surface and the foaming power of FTAI aqueous solution and FTAI aqueous solution with 0.1 mol/L NaCl were measured.The results showed that this fluorinated surfactant exhibits excellent surface activity at room temperature.Its foaming power and wetting power were much higher than that of conventional cationic surfactant C12H25N+(CH3)3Cl-.
