Description
Summary:Thermodynamic calculations and experimental studies have demonstrated that the regeneration of fluorine from the fluorine-containing byproducts and wastes of contemporary industry is reasonable to be performed in the form of hydrogen fluoride via the processing of fluorine-containing compounds in a hydrogen-containing fuel–oxygen-containing oxidant flame. The considered sources of feedstocks for the synthesis of hydrogen fluoride are hydrofluoric acid, including acid of azeotropic composition, uranium hexafluoride, carbon tetrafluoride, nitrogen trifluoride, ammonium bifluoride, silicon tetrafluoride, hexafluorosilicic acid, and hexafluorosilicates.
