Manufacture of 3,3,4,4-tetrahydroperfluoroalkanoates |
摘要 |
Esters and other carboxylic acid derivatives of 3,3,4,4-tetrahydroperfluoroalkylcarboxylic acids are made by the iron promoted reaction of an ester of bromodifluoroacetic acid or other carboxylic acid derivatives and a (perfluoroalkyl)ethylene. The resulting products may be converted to the corresponding alkali metal or ammonium carboxylate slits which are useful as surfactants in fluoroolefin polymerizations.
