FLUORINE PRODUCTION PROCESS Russian patent published in 2004 - IPC

Abstract RU 2221739 C1

FIELD: inorganic compounds technology. SUBSTANCE: fluorine is produced from solid-phase metal fluorides and their complex salts via thermal decomposition. Process is carried out by heating to 150-400 C salts of metals in high oxidation state in the form of granules or tablets 1.0 to 3.0 mm in size. Temperature gradient in the bed upon heating does not exceed 15 C. In particular, starting salts utilized are MnF₄, and other salts such as K₃NiF₇, K₂NiF₆, K₂CuF₆, and related compounds. EFFECT: increased yield of fluorine (up to 99%) and simplified technology. 1 dwg, 1 tbl, 7 ex
