A method for the production of nitrogen trifluoride from a fluorine reactant and an ammonium ion source that is dispersed within a liquid phase reaction mixture containing one or more perfluorocarbon fluids is disclosed herein. In one embodiment, the fluorine reactant is introduced to the reaction mixture at a temperature that ranges from 90 C. to 120 C. In this embodiment, the percentage yield of nitrogen trifluoride may be about 80% or greater.
