This article shows the feasibility and possibility of developing a universal industrial method for producing hydrogen fluoride from fluorine-containing wastes and by-products of modern industries (depleted uranium hexafluoride, hydrofluorosilicic acid, ammonium bifluoride, carbon tetrafluoride, and other perfluorocarbons and hydrofluorocarbons, sulfur hexafluoride, nitrogen trifluoride, mixtures containing sodium hexafluoroaluminate, etc.) as alternatives to the conventional industrial method of natural calcium difluoride decomposition with sulfuric acid. As the main process method, we suggest fluoride reduction in a flame of hydrogen-containing fuel and oxygen-containing oxidant, due to the unique thermodynamic stability of hydrogen fluoride. The paper presents the results of thermodynamic calculation and experiments on the proposed method for various fluorides -uranium hexafluoride, carbon tetrafluoride, silicon tetrafluoride, ammonium bifluoride, etc. As a fuel, we consider methane, hydrogen and ammonia as an oxidizing agent, oxygen and air. For the case where water is present in the combustion products, we discuss various dehydrogenation options of hydrofluoric acid. We have demonstrated that the industrial cost hydrogen fluoride produced from the above-listed fluorides is approximately twofold lower than the same parameters for the conventional method of fluorite decomposition using sulfuric acid.

“…Given the environmental and security concerns over its storage, a recent article critically discusses the methods by which the material be reconverted to uranium oxides and either HF or high value fluorine based reagents such as COF 2 , WF 6 , MoF 6 , PF 5 , SF 4 , SiF 4 or SF 6 . 7 Fluorination methods, including nucleophilic fluorination, electrophilic fluorination and trifluoromethylation using continuous-flow microreactors are currently under development. Compared to batch methods, they offer automation and reaction optimization with efficiency gains through generation of less waste, lower solvent use and reduced exposure to reactive intermediates.…”
