PERFLUOROALKYLDICHLOROETHYLENES AND PRODUCTION OF PERFLUOROALKANECARBOXYLIC ACIDS
1. Process for preparing perfluoroalkane-carboxylic acids RF CO2 H wherein RF denotes a straight-chain or branched perfluoroalkyl radical containing from 1 to 20 carbon atoms, characterized in that a perfluoroiodo-alkane RF I is reacted with trichloroethylene in an acidic solvent in the presence of...

description | 1. Process for preparing perfluoroalkane-carboxylic acids RF CO2 H wherein RF denotes a straight-chain or branched perfluoroalkyl radical containing from 1 to 20 carbon atoms, characterized in that a perfluoroiodo-alkane RF I is reacted with trichloroethylene in an acidic solvent in the presence of zinc, and then the resulting 2-perfluoroalkyl-1,1-dichloroethylene RF CH = CCI2 is oxidised in a basic medium with the aid of potassium or sodium permanganate at a temperature of at least 80 degrees C. |
