Abstract
Official abstract text for this publication.
There is provided an anode for electrolytic synthesis capable of electrolytically synthesizing fluorine gas or a fluorine containing compound by a simple process and at a low cost while suppressing the occurrence of an anode effect. An anode for electrolytic synthesis ( 3 ) for electrolytically synthesizing fluorine gas or a fluorine containing compound includes an anode substrate formed of a carbonaceous material and a metal coating film coating the anode substrate. Metal constituting the metal coating film is nickel.
First claim

1 . An anode for electrolytic synthesis for electrolytically synthesizing fluorine gas or a fluorine containing compound, the anode for electrolytic synthesis comprising: an anode substrate formed of a carbonaceous material; and a metal coating film coating the anode substrate, wherein metal constituting the metal coating film is nickel. 2 . The anode for electrolytic synthesis according to claim 1 , wherein a mass of the nickel constituting the metal coating film is 0.03 mass % or more and 0.4 mass % or less of a mass of an electrolytic solution used for the electrolytic synthesis. 3 . The anode for electrolytic synthesis according to claim 1 , wherein the mass of the nickel constituting the metal coating film is 0.01 g or more and 0.1 g or less per cm 2 of a surface of the anode substrate. 4 . A method for producing fluorine gas or a fluorine containing compound comprising: electrolyzing an electrolytic solution containing hydrogen fluoride using the anode for electrolytic synthesis according to claim 1 . 5 . A method for producing fluorine gas or a fluorine containing compound comprising: performing pre-electrolysis of electrolyzing moisture contained in an electrolytic solution containing hydrogen fluoride, and then electrolyzing the electrolytic solution containing hydrogen fluoride using the anode for electrolytic synthesis according to claim 1 . 6 . The anode for electrolytic synthesis according to claim 2 , wherein the mass of the nickel forming the metal coating film is 0.01 g or more and 0.1 g or less per cm 2 of a surface of the anode substrate. 7 . A method for producing fluorine gas or a fluorine containing compound comprising: electrolyzing an electrolytic solution containing hydrogen fluoride using the anode for electrolytic synthesis according to claim 2 . 8 . A method for producing fluorine gas or a fluorine containing compound comprising: electrolyzing an electrolytic solution containing hydrogen fluoride using the anode for electrolytic synthesis according to claim 3 . 9 . A method for producing fluorine gas or a fluorine containing compound comprising: performing pre-electrolysis of electrolyzing moisture contained in an electrolytic solution containing hydrogen fluoride, and then electrolyzing the electrolytic solution containing hydrogen fluoride using the anode for electrolytic synthesis according to claim 2 . 10 . A method for producing fluorine gas or a fluorine containing compound comprising: performing pre-electrolysis of electrolyzing moisture contained in an electrolytic solution containing hydrogen fluoride, and then electrolyzing the electrolytic solution containing hydrogen fluoride using the anode for electrolytic synthesis according to claim 3 .
