摘要: The invention relates to a method for producing 1,1,2,2,3,3,4-heptafluorocyclopentane. This method includes the step of reducing 1,1-dichlorooctafluorocyclopentane by hydrogen in the presence of a hydrogenation catalyst. This catalyst contains at least one first metal selected from metals of 8, 9, and 10 groups of periodic table, such as iron, cobalt, palladium, platinum, rhodium, ruthenium, iridium, and osmium. According to this method, it is possible to produce 1,1,2,2,3,3,4-heptafluorocyclopentane with high yield and high selectivity.

摘要: The invention relates to a method for preparing a fluorinated product that is a first perhalogenated five-membered cyclic compound (e.g., 1,2-dichlorohexafluorocyclopentene and 1,1-dichlorooctafluorocyclopentane). This method includes reacting in a gas phase a starting material that is a second perhalogenated five-membered cyclic compound having at least one unsaturated bond, at substantially the same time with chlorine and hydrogen fluoride, in the presence of a fluorination catalyst containing an activated carbon optionally carrying thereon a metal compound, thereby to decrease the number of the at least one unsaturated bond and to increase the number of fluorine atoms of the second compound. The method is appropriate for the production of the first perhalogenated five-membered cyclic compound in an industrial scale.

摘要: An optical disk apparatus is provided with a recording/reading unit that records data and reads recorded data with respect to an optical disk. Further, the optical disk apparatus is provided with a control unit that judges whether an account name recorded on the optical disk matches an account name selected by the operation unit. The control unit permits the recording/reading unit to record data to the optical disk if the account names match. And the control unit prohibits the recording/reading unit from recording data to the optical disk if it is judged that the account names do not match.
