Abstract:
A process for preparing a compound having at least 4 carbon atoms and represented by the following formula (3), characterized in that a compound having at least 4 carbon atoms and represented by the following formula (1) is hydrogenated in the presence of a noble metal catalyst in the liquid phase or the vapor phase:R1â€”C1Cl&boxH;C2Fâ€”R2â€ƒâ€ƒ(1) wherein C1 and C2 designate two carbon atoms of the compound; and wherein R1 is an alkyl group having 1 to 8 carbon atoms which may be fluorinated, and R2 is an alkyl group having 1 to 8 carbon atoms which may be fluorinated, and R1 and R2 may form together a divalent hydrocarbon group having 2 to 8 carbon atoms represented by the formula â€”R1â€”R2â€”, in which the entirety or a part of the hydrogen atoms in the hydrocarbon group of formula â€”R1â€”R2â€” may be fluorinated, and which forms together with C1 and C2 an alicyclic compound; R1â€”C1H2â€”C2HFâ€”R2â€ƒâ€ƒ(3).
