    摘要: A novel fine carbon fiber is produced by vapor growth, in which a graphite-net plane consisting of carbon atoms alone forms a temple-bell-shaped structural unit comprising closed head-top part and body-part with open lower-end, where an angle θ formed by a generatrix of the body-part and a fiber axis is less than 15°, 2 to 30 of the temple-bell-shaped structural units are stacked sharing a central axis to form an aggregate, and the aggregates are connected in head-to-tail style with a distance, thereby forming a fiber. Furthermore, a fine short carbon fibers with excellent dispersibility can be obtained by shortening the fine carbon fiber.

    摘要: In the process for producing a cyclododecanone by isomerizing an epoxycyclododecane-containing starting material in the presence of an isomerization reaction catalyst containing lithium bromide and/or lithium iodide, in order to perform the reaction with high efficiency (high reaction rate) and high selectivity and stably produce a high-purity cyclododecanone in industry while maintaining a high-level reaction rate, the epoxycyclododecane-containing starting material is produced by contacting an epoxycyclododecadiene with hydrogen in the presence of a hydrogen-reduction catalyst and has a content of the hydroxyl group-containing cyclododecane compounds contained in the epoxycyclododecane-containing starting material controlled to 5 mol % or less.

    摘要: Disclosed is a method for producing a biphenyltetracarboxylic acid ester by oxidative coupling a phthalic acid ester by using a catalyst comprising at least a palladium salt, a copper salt and a β-dicarbonyl compound in the presence of a molecular oxygen, wherein the β-dicarbonyl compound is supplied into a reaction mixture liquid intermittently at an interval of less than 30 minutes, or continuously. This method allows, in particular, the selective and economical production of an asymmetric biphenyltetracarboxylic acid tetraester such as 2,3,3′,4′-biphenyltetracarboxylic acid tetraester.
