description FIELD: industrial inorganic synthesis. ^ SUBSTANCE: invention relates to production of nitrogen trifluoride used in chemical industry as fluorination agent and fluorine-containing raw material as well as oxidant for high-calorific fuels, as component of working media in high-emission power lasers, etc. Process consists in electrolysis of hydrogen fluoride solutions of ammonium fluoride in electrolysis cells with carbon anodes, including dehydration and basic electrolysis processes and replacement of consumed substances during electrolysis. Dehydration electrolysis is started at cell voltage 3.0 v and conducted while lowering anodic current density to 0.005 A/cm2 to produce anodic gas with volume fraction of nitrogen trifluoride no higher than 0.05%. Basic electrolysis is conducted while raising anodic current density to 0.1 A/cm2. ^ EFFECT: reduced formation of tetrafluoromethane in basic electrolysis and lowered power consumption of electrochemical nitrogen trifluoride synthesis process. ^ 2 cl, 1 tbl, 3 ex
