Abstract
A process and an anode for the production of nitrogen trifluoride or fluorine where the anode in the electrolytic cell is made primarily from mesocarbon microbeads. The mesocarbon microbead anodes minimize the production of CF4 and improve the purity of the nitrogen trifluoride or fluorine gas produced. Additionally, the anodes may be molded, instead of extruded or machined, providing for improved dimensional and mechanical integrity of the anode.
Claims26
A process of producing nitrogen trifluoride or fluorine comprising:
- performing electrolysis of an electrolyte by using an electrolytic anode comprising primarily mesophase carbon to obtain nitrogen trifluoride or fluorine.
An electrolytic cell for producing nitrogen trifluoride or fluorine comprising:
- an anode comprising mesocarbon microbeads;
- a cathode;
- and
- an electrolyte composition comprising HF, optionally KF, and optionally NH4F,
- wherein the electrolytic cell is operated to produce nitrogen trifluoride or fluorine.
An anode comprising mesocarbon microbeads that are ungraphitized.
