PROCESS FOR PREPARING FLUORINATED C4 TO C6HYDROCARBONS AND NOVEL CYCLIC FLUORINATEDHYDROCARBONS AND THEIR USE AS PROPELLANT GASAND WORKING FLUID FOR HEAT PUMP SYSTEMSABSTRACT OF THE DISCLOSUREThis invention relates to a process for preparingfluorinated C4 to C6 hydrocarbons by catalyticallyhydrogenating, in the presence of a base, at leastpartially halogenated olefins. This invention alsorelates to certain novel cyclic fluorinated C5 and C6hydrocarbons prepared by the process of this invention.This invention further relates to the use of fluorinatedC4 to C6 hydrocarbons as propellant gas or as workingfluid for heat pump systems.
