The present invention provides a process for the preparation of luorinated alkanes. The process comprises the step of: reacting an alkene with carbon having fluorine absorbed therein at a temperature and for a time sufficient to form fluorinated alkanes. The alkene used is not perhalogenated at the double-bonded carbons. Preferably, the alkene used is vinylidene fluoride or ethylene. The process produces products such as 1,1,1,2-tetrafluoroethane (known in the art as 134a) which may be used as a refrigerant and 1,1,1-trifluoroethane (known in the art as R143a) and 1,2-difluoroethane (known in the art as R152) which may be used as blowing agents or solvents. |
