Abstract
The present invention is directed to an improved reaction process that allows for the achievement of excellent NFproduction yields, while minimizing the amount of unreacted fluorine exiting with the process gases and minimizing the amount of liquid melt waste (HF/NH) produced by the process. The basic NFprocess resides in reacting Fwith an ammonium ion source, e.g., ammonium acid fluoride, under conditions for forming NF. The improvement in the process comprises:
