Aiming at the preparation of fluorine-containing surfactant an amidoamine (3) was synthesized from perfluorooctanoic acid (1) and N, N-dimethylaminopropylamine. (3) was reacted with methyl iodide or dimethyl sulfate to prepare quaternary salt (4 or 5) and also with propanesultone to obtaine sulfobetaine-type surfactant (6).
Surface active properties of these surfactants were determined regarding surface tension, critical micelle concentration, solubilization and oil-repellency.
