Reaction Conditions

Reaction Steps

One percent by weight of n-tridecane (dielectric constant 2.0), a low-polarity compound, was dissolved in crude 1,3,3,4,4,5,5-heptafluorocyclopentene having a purity of 99.9 GC %. An autoclave having a capacity of 100 ml was charged with a catalyst of activated carbon having supported thereon 5% by weight of powdered palladium. After the deaeration under reduced pressure, n-tridecane-containing 1,3,3,4,4,5,5-heptafluorocyclopentene prepared previously was poured. While the mixture was stirred at 40° C., the reaction was conducted by repeating block charge of hydrogen at a gauge pressure in the range of 0 to 6 kgf/cm2. After the completion of the reaction, the product was analyzed through gas chromatography. Consequently, a fluorinated saturated hydrocarbon containing 94 mol % of 1,1,2,2,3,3,4-heptafluorocyclopentane (HFCPA) and 6 mol % of 1,1,2,2,3,3-hexafluorocyclopentane was obtained.
