FIELD: industrial organic synthesis. SUBSTANCE: saturated aliphatic perfluorocarbons are prepared by double-phase fluorination of carbon at elevated temperature at stirring and fluorine-to-carbon weight ratio 1:(20-1000) in two stages: fluorination at 450-600 C for 0.3-1.5 s followed by keeping solid phase in fluorine-free atmosphere at 400-600 C for 100-500 s while continuously removing gaseous products. EFFECT: enabled production of perfluorocarbons containing more than 4 carbon atoms. 1 dwg, 1 tbl, 24 ex
