| Description |
Electrochemical perfluorination (ECPF) of nhexanoyl,
n-heptanoyl, n-octanoyl, n-nonanoyl and ndecanoyl
chlorides was carried out under identical experimental
conditions in liquid HF. The product distribution
among perfluorinated carboxylic acids, perfluoro ethers,
perfluoroalkanes, isomerised and fragmented products
containing less number of carbon atoms was identified
using 19F NMR. The selectivity of C6–C10 perfluoro carboxylic
acid varied between 29 and 36%. The alkali
insoluble perfluoro cyclic ether and perfluoro alkane fractions
increased with increasing chain length. The increase
of perfluoroalkane fractions is mainly due to decarboxylation.
Cyclic ether fractions also decreased slightly with
increase in chain length. Among the cyclic ethers a
substituted oxolanes were the predominant products. Six
membered cyclic ethers were always found to contain b
substitution. The possible pathways for these products are
also indicated.
