FIELD: chemistry.
SUBSTANCE: method of chemical graphite modification includes interaction of natural graphite with potassium salts of perfluoro(ω-chloroperfluoro)carbonic acids in presence of potassium persulfate at temperature 90-95°C in water medium. Separation of target product is performed by filtering and washing with hot water, with further drying in the air at temperature 120-130°C.
EFFECT: creation of more technological process of obtaining fluorographite and improvement of its anti-friction properties.
