FIELD: chemistry.
SUBSTANCE: method of hydrofluoroalkane synthesis involves introduction of at least on chlorine-containing or chlorine and fluorine-containing hydrofluoroalkane precursor with atomic F/Cl ratio under 1 in fluid phase into reaction with hydrogen fluoride in liquid medium where weight content of fluorine-containing or chlorine and fluorine-containing organic compounds with atomic F/Cl ratio of at least 1 is maintained at 50% or higher.
EFFECT: increased product output.
