ABSTRACT:
Cationic fluorochemical surfactants useful as antistatic agents and lubricants for polymeric shapes are prepared from 2,2,3,4,4,4-hexafluorobutanol or perfluorobutyric acid. Hexafluorobutanol is reacted with bromoundecanoic acid to obtain a bromoester which is then reacted with pyridine to obtain a cationic surfactant. Perfluorobutyric acid is esterified with methanol to obtain methyl perfluorobutyrate which is then reacted with dimethylaminopropylamine to obtain an amino-amide which is then reacted with hydrogen peroxide to obtain the N-oxide derivative which is neutralized with glycolic acid to obtain a cationic surfactant, a salt of the N-oxide derivative.
