The present invention relates to perfluoroalkyl substituted sulfates and salts thereof of the formulas (Rf X CH2)xC(CH2OH)y(CH2OSO3-M+)z (I) or (RfE X CH2)xC(CH2OH)y(CH2OSO3-M+)z (II) which are prepared by sulfation of perfluoroalkyl substituted alcohols of the formulas (Rf X CH2)xC(CH2OH)q (III) or (RfE X CH2)xC(CH2OH)q (IV) wherein Rf is a straight or branched chain perfluoroalkyl of 1 to 18 carbon atoms or said perfluoroalkyl substituted by perfluoroalkyl of 2 to 6 carbon atoms, or mixtures thereof, E is branched or straight chain alkylene of 1 to 10 carbon atoms or said alkylene interrupted by one to three groups selected from the group consisting of -NR-, -O-, -S-, -SO2-, -COO-, -OOC-, -CONR-, -NRCO-, -SO2NR- and -NRSO2 or terminated at the Rf end with -CONR- or -SO2NR-, where Rf is attached to the carbon or sulfur atom, and for formula II, X is -S-, -O-, SO2-, or -NR-, and for formula I, X is -CONR- or -SO2NR-, where Rf is attached to the carbon or sulfur atom, and where R is independently hydrogen, alkyl of 1 to 6 carbon atoms or hydroxyalkyl of 2 to 6 carbon atoms; x is 1,2 or 3; y is 0, 1 or 2; z is 1, 2 or 3; q is 1,2 or 3; x+y+z=4 and x+q=4; M is independently hydrogen, an alkali metal or organoammonium ion. |
