    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: A process for producing an aryl carbamate of a high purity at a high yield by reacting a diaryl carbonate with an amine compound having one or more hydrogen atoms bonded to the N position in the presence of carboxylic acid(s) of the following general formulae (I): R.sup.1 --COOH and/or (II): R.sup.2 --COOH (wherein R.sup.1 represents an alkyl or cycloalkyl group having an .alpha.-positioned carbon atom bonded to only one hydrogen atom, an alkyl group having an .alpha.-positioned carbon atom bonded to no hydrogen atom, or an aryl or heterocyclic group, and R.sup.2 represents an alkyl group having an .alpha.-positioned carbon atom bonded to two or more hydrogen atoms).

    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.
