A fluorinated saturated hydrocarbon which is an acyclic or cyclic fluorinated saturated hydrocarbon characterized by comprising 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, Rf1 and Rf2 each represents a perfluoroalkyl group, a fluorine atom or a hydrogen atom, at least one thereof is a perfluoroalkyl group, and further Rf1 and Rf2 may be bound to each other to form a ring by a perfluoroalkylene chain)
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 fluorinated saturated hydrocarbon containing, in a high proportion, trihydrofluorocarbon which is excellent especially in the chemical stability and high in the safety for living bodies among hydrofluorocarbons (HFC) known to have zero ozone depletion potential and to have a small global warming potential.
