ABSTRACT:
Perfluoro-n-heptane is produced by an electrochemical fluorination process comprising cooling the effluent from a first cell to a temperature sufficient to condense such effluent, separating a fluorocarbon-rich phase from the condensate, a second stage fluorination wherein partially fluorinated n-heptanes in the fluorocarbon-rich phase are further fluorinated and separation of perfluoro-n-heptane from the second stage effluent by simple fractionation.
