Fluorinated organic substances anodic oxidation

It has to be considered that titanium - at least without special protection layers - will be attacked by several chemicals for example, fluorides, fluorine-containing substances, such as tetrafluo-roborates BF4, or oxalates, and possibly by other organic acids, which may be formed during anodic oxidation reactions. An application of titanium in nonaqueous media is not suitable (instability of the passivating oxide layer). 

Simons process — Electrochemical polyfluorination reactions of organic compounds are the only efficient way to industrial production of perfluorinated compounds. The reaction proceeds in the solution of KF in liquid HF (b.p. 19.5 °C), where the starting substances as alcohols, amines, ethers, esters, aliphatic hydrocarbons and halo-hydrocarbons, aromatic and heterocyclic compounds, sulfo- or carboxylic acids are dissolved. During anodic oxidation, splitting of the C-H bonds and saturation of the C=C bonds occur and fluorine atoms are introduced.
