Title:
PRODUCTION OF GASEOUS NITROGEN TRIFLUORIDE
Document Type and Number:
Japanese Patent JPH0551778
Kind Code:
A
Abstract:
PURPOSE:To suppress revelation of anode effect in a production of nitrogen trifluoride using a carbon electrode. CONSTITUTION:When producing nitrogen trifluoride by electrolysis using an ammonium fluoride-hydrogen fluoride two component molten salt as an electrolyte, in nitrogen trifluoride and dinitrogen monoxide generated by electrolizing at <50mA/cm<2> anode current density, anode current is switched over, when volume ratio of the dinitrogen monoxide to the nitrogen rtifluoride gas becomes <=0.03, and electrolysis is executed in >=50mA/cm<2> anode current density. In the result, revelation of anode effect is suppressed and dissolution of anode, contamination of electrolyte is prevented.
