Abstract: A composition containing less than 95 mol % of a trihydrofluorinated saturated hydrocarbon represented by the following formula (I) Rf1—R1—Rf2  (I) (wherein R1 represents a carbon chain in which CHF and CH2 are bound, and Rf1 and Rf2 are bound to each other to form a ring by a perfluoroalkylene chain of 2 to 4 carbon atoms) and the balance of a tetrahydrofluorinated saturated hydrocarbon having the same carbon number and the same carbon structure as the trihydrofluorinated saturated hydrocarbon, as represented by the following formula (II) Rf1—R2—Rf2  (II) (wherein R2 represents a carbon chain in which CH2 and CH3 are bound, and Rf1 and Rf2 are as defined above) is provided as a composition containing, in a high proportion, trihydrofluorocarbon, a hydrofluorocarbon (HFC) known to have a small global heating coefficient, which has less influence on the global environment, shows less toxicity to animals, and is chemically stable.

Abstract: Compounds each having a —CH2—CHF— group and a number of carbon atoms of 4 or above are prepared by hydrogenating a compound having a —CCl═CF— group and a number of carbon atoms of 4 or above in the presence of a noble metal catalyst in a liquid or gas phase. The compound having a —CCl═CF— group and a number of carbon atoms of 4 or above is preferably a C4-C10 alicyclic one, and can be prepared by reacting a compound having a —CCl═CCl— group and a number of carbon atoms of 4 or above with a fluorinating agent.
