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:.

A process for reducing or eliminating NH/HF/MFz liquid waste melt in the manufacture of NFis provided which includes the steps of providing an NFreactor for a reaction of Fwith a liquid NH/HF/MFz mixture that produces NF, HF, Nand other nitrogen fluorides as gaseous products and a liquid NH/HF/MFz mixture as the liquid waste melt. The process further provides for reduction or elimination of the liquid NH/HF/MFz waste melt produced by the reactor.

This invention is an apparatus and a method for continuously generating a hydride gas of metal Mwhich is substantially free of oxygen in a divided electrochemical cell. An impermeable partition or a combination of an impermeable partition and a porous diaphragm can be used to divide the electrochemical cell. The divided electrochemical cell has an anode chamber and a cathode chamber, wherein the cathode chamber has a cathode comprising metal M, the anode chamber has an anode capable of generating oxygen, an aqueous electrolyte solution comprising a metal hydroxide MOH partially filling the divided electrochemical cell. Hydride gas generated in the cathode chamber and oxygen generated in the anode chamber are removed through independent outlets.
