A novel compound, 3,3-dichloro-1,1,1,2,2,4,4,5,5,5-decafluoropentane, as a precursor of a substitute for refrigerants and the like; an economical process for continuously producing the compound in high yield and selectivity by reacting tetrafluoroethylene with difluorodichloromethane in the presence of a Lewis acid catalyst; and a process for producing 1,1,1,2,2,4,4,5,5,5-decafluoropentane in a high yield by reducing the dichlorodecafluoropentane. |
