PURPOSE:To prepare purified graphite fluoride useful as an active substance of cell, etc. free from a bad smell and corrosive properties, by treating graphite fluoride with an ammonia gas so that remaining unliked fluorine is removed. CONSTITUTION:The crude graphite fluoride 3 is packed on the porous plate 2 of the purification column 1, NH3 introduced from the pipe 5 is brought into contact with it for about 5min-48hr while it is heated by the heater 4 at room temperature - about 200 deg.C, unreacted NH3 and the reaction product are discharged from the pipe 6, to give graphite fluoride containing no unlinked fluorine. |
