A process for manufacturing fluoroolefins comprising perfluorinating a starting material comprising at least one carbon-bonded hydrogen by electrochemical fluorination, dissociating this separated effluent in a pyrolysis, quenching and separating the effluent to yield tetrafluoroethylene and/or hexafluoropropylene.

Process for manufacturing fluoroolefins

A method of treating a fluorocarbon feedstock includes generating, in a high temperature zone, an electrical arc between at least one cathode and at least one anode, generating in the high temperature zone and by means of the electrical arc and a plasma gas, a thermal plasma having a tail flame, allowing a fluorocarbon feedstock comprising at least one fluorocarbon compound to form a reactive thermal mixture with the thermal plasma tail flame, with the fluorocarbon compound dissociating into at least one fluorocarbon precursor or reactive species having fewer carbon atoms than the fluorocarbon compound, and cooling the reactive thermal mixture to form, from the fluorocarbon precursor or reactive species, a fluorocarbon product.

Treatment of fluorocarbon feedstocks

The present invention provides a catalytic process for preparing perfluoroethanesulfonyl fluoride and/or perfluorodiethylsulfone using a two-part catalytic process comprising a metal fluoride and a crown ether.

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.

Fluorine cell

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.
