Process for the electrochemical fluorination of a hydrocarbon substratum

Process for the electrochemical fluorination of a hydrocarbon substrate in the presence of a HF-containing electrolyte under electrochemical fluorination conditions to a fluorinated product and a hydrogen gas by-product, the improvement of which comprises additional steps of (a) continuously separating the formed fluorinated product from the electrolyte by extracting the electrolyte with an extraction agent, (b) continuously separating residual amounts of the fluorinated product from the hydrogen gas by-product by extraction of the gas with an extraction agent; and (c) recovering the fluorinated product by distillation of the extraction agent from step (a) and step (b).
