Abstract
Abstract Fluorocarbon compounds of the formula WHEREIN R1 and R2 are F, fluoroalkyl or fluoroalkylene groups forming a cycloaliphatic structure, wherein -(CZ1Z2-CZ3Z4)- and (CX1X2-CX3X4)- are bifunctional groups wherein Z1-Z4 and X1-X4 are H, F, or Cl, and wherein Y is -CN or WHEREIN Q represents F, Cl, hydroxy, alkoxy, amino or substituted amino groups are prepared from polyfluorohalides of the formula WHEREIN E is a halogen. Carboxylic acids of the present invention and their amides are oil and stain repellent agents. Their salts, esters, halides and nitriles are surfactants and/or intermediates for the preparation of oil and stain repellent agents.
