    摘要： Perfluorinated carboxylic acids and their fluorides of the formula RF(CF2CF2)n-1 CF2COB wherein RF is a perfluoroalkyl radical, B is OH or F, and n is an integer from 1 to 7 are made by reacting a fluoroalkyl iodide of the formula RF(CF2CF2)nI molar ratio AT A TEMPERATURE OF 50* TO 120*C with oleum in the presence of a salt of a metal of Group IIB of the Periodic Table while adding chlorine, the molarratio ofSO3 to perfluoroalkyl iodide being between 2.5 : 1 and 10 : 1. This is followed by isolating the formed perfluorocarboxylic acid fluoride or by hydrolyzing the fluoride to the corresponding perfluorocarboxylic acid.

    摘要： New perfluoroalkylalkylcarboxylic acids of the formula ##EQU1## are provided, wherein R.sub.f is an unbranched or branched perfluoroalkyl radical with 3 to 18 carbon atoms, R.sub.1 is hydrogen or fluorine and m is a whole number from 1 to 3.The new compounds are suitable for producing water and oil-repellent finishes, soil-release and antisoiling effects on porous and non-porous substrates. They are further valuable intermediates for the manufacture of fluorinated compounds which may be used in the same field as the inventive compounds.
