  • Fluorine cell
    Patent number: 6146506
    Abstract: An electrochemical cell for the production of fluorine includes an anode having a carbon portion partially or fully impregnated with a polymeric material and a conductive centrally disposed internal channel that permits the anode to be run at high current with uniform current densities without undue resistance heating.
    Type: Grant
    Filed: March 6, 1995
    Date of Patent: November 14, 2000
    Assignee: 3M Innovative Properties Company
    Inventors: Gerald L. Bauer, William Ves Childs
  • Anodic electrode for electrochemical fluorine cell
    Patent number: 6063255
    Abstract: Carbon electrodes for use as an anode in electrochemical cells for the generation of fluorine by electrolysis of molten KF.multidot.2HF electrolyte. Also included is a process for the operation of an electrochemical fluorine cell in combination with a direct fluorination reactor.
    Type: Grant
    Filed: January 14, 1994
    Date of Patent: May 16, 2000
    Assignee: 3M Innovative Properties Company
    Inventors: Gerald Lee Bauer, William Ves Childs, Charles Frederick Kolpin, Dean Thomas Rutten
  • Production of perfluoro-n-heptane
    Patent number: 4035250
    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.
    Type: Grant
