METHOD OF PRODUCING PENTAFLUOROIODOETHANE Russian patent published in 2018 - IPC C07C17/363 C07C19/16 

FIELD: chemistry.

SUBSTANCE: invention relates to the method of producing pentafluoroiodoethane from perfluoro-propene, which includes the interaction of CF₃CF=CF₂ with the iodine source, such as iodine-halide I-I, I-Br, I-Cl in the presence of inorganic fluoride, or perfluoro-isopropyl-iodide, and sodium methylate in the polar aprotic solvent with the formation of 1,1,1,2,3,3-hexafluoro-2-iodine-3-methoxy-propane, its subsequent demethylation by boiling with pentachloride antimony with obtaining 2,3,3,3-tetrafluoro-2-iodopropionyl fluoride, and decarbonylation of the latter under the action of pentafluoride antimony on heating, which gives pentafluoroiodetane.

EFFECT: use of available non-explosive raw materials.
