Method for producing fluorine gas |
| abstract |
Provided is a method for producing fluorine gas in which by-product hydrogen fluoride produced by reacting a raw material compound with fluorine gas for fluorination and producing a fluoride of a target component can be reused as a raw material for fluorine gas production by an electrolytic method. A method for producing fluorine gas includes a fluorination step of obtaining a reaction mixture containing a main fluoride of a target component produced by fluorination of a raw material compound and a by-product hydrogen fluoride, and separating the reaction mixture, the main component containing the main fluoride and A separation process of obtaining a by-product component containing by-product hydrogen fluoride, a purification process of purifying the by-product component, reducing the concentration of organic matter contained in the by-product component, and a purification process of obtaining a recovered hydrogen fluoride component having an increased concentration of by-product hydrogen fluoride; and recovered hydrogen fluoride An electrolysis step of producing a fluorine gas by performing electrolysis using a component as at least a part of the electrolytic solution, and an introduction step of introducing the fluorine gas obtained in the electrolysis step into a fluorination reaction field in the fluorination step. |
