摘要: A process for the preparation of an alkane containing fluorine which process comprises contacting a halogenated alkane containing at least one halogen atom selected from chlorine, bromine and iodine with a transition metal oxide fluoride and replacing at least one chlorine, bromine or iodine atom in said halogenated alkane by a fluorine atom.The transition metal oxide fluoride may be an oxide fluoride of vanadium, molybdenum, tungsten, rhenium or osmium, and the replacement of halogen atom in the starting halogenated alkane is highly selectove where the starting halogenated alkane also contains hydrogen.
