| 摘要 |
The instant invention relates to compounds of the formula <IMAGE> wherein each Rf is independently straight or branched chain perfluoroalkyl of 2 to 18 carbon atoms or perfluoroalkoxy-perfluoroalkyl of 4 to 18 carbon atoms; each R1 is independently straight or branched chain alkylene of 1 to 12 carbon atoms, alkylenethioalkylene of 2 to 12 carbon atoms, alkyleneoxyalkylene of 2 to 12 carbon atoms, or alkyleneiminoalkylene of 2 to 12 carbon atoms where the imino nitrogen atom contains as a third substituent, hydrogen or alkyl of 1 to 6 carbon atoms; R2, R3 and R4 are independently hydrogen, chloro, bromo, alkyl of 1 to 6 carbon atoms, alkenyl of 2 to 6 carbon atoms, hydroxyalkyl of 1 to 6 carbon atoms or alkoxy of 1 to 6 carbon atoms, and R2 and R3 additionally may, together with the carbon atoms to which they are attached, form a fused benzo ring; R5 is hydrogen, or alkyl of 1 to 6 carbon atoms which is unsubstituted or substituted by hydroxy, alkoxy of 1 to 6 carbon atoms or phenyl; x is 0, 1 or 2; and the alkali metal, alkaline earth metal, ammonium or amine salt thereof. These compounds are useful as surfactants, water repellents and intermediates.
