ON POLYFLUORINATED, HF SOLUBLE COMPOUNDS FORMED DURING THE ELECTROCHEMICAL FLUORINATION OF DIBUTYLMETHYLAMINE

The electrochemicaI fluorination of dibutylmethylamine yields, besides other products, considerable amounts of polyfluorinated compounds which remain dissolved in HF. Since the occurrence of such compounds is a widespread phenomenon in ECF, their formation as well as their composition was studied. Whereas some partially fluorinated compounds are likely to be intermediates in the fluorination process, others remain inert toward further ECF. The latter have on average about 9 of the 21 H-atoms replaced by F, with almost no F at C-atoms adjacent to the N-atom. © 1990.
