    摘要: A method of producing optically active trans-2-aminocyclohexanol includes allowing racemic trans-2-aminocyclohexanol to react with optically active 2-methoxyphenylacetic acid to produce an optically active 2-methoxyphenylacetic acid salt of optically active trans-2-aminocyclohexanol and separating the salt. An optically active 2-methoxyphenylacetic acid salt of optically active trans-2-aminocyclohexanol is also provided. The method makes it possible to produce optically active trans-2-aminocyclohexanol with ease and a high yield from an industrially-advantageous, inexpensive raw material.

    摘要: When a salt of an amine and an optically active diacyltartaric acid, or a diastereomer salt of an optically active amine and an optically active diacyltartaric acid, obtained by optically resolving a racemic amine using the optically active diacyltartaric acid, is salt-exchanged with an acid aqueous solution, the optically active diacyltartaric acid is added in the acid aqueous solution beforehand.Furthermore, a raw material containing a racemic amine and an optically active diacyltartaric acid is optically resolved, and the diastereomer salt of the optically active amine and the optically active diacyltartaric acid respectively of one isomer type, is separated. The obtained diastereomer salt is dissociated using an acid aqueous solution containing the optically active diacyltartaric acid, for recovering the optically active diacyltartaric acid, and the obtained optically active diacyltartaric acid is recycled into an optical resolution step as a raw material of the optical resolution step.

    摘要: The present invention provides a wire for a press-connecting terminal which has a high flexibility, and achieves a high reliability for a connection portion at the time of press-connection, and also provides a method of producing a conductor of such a wire. The wire provides a stranded conductor and an insulator covering the conductor. Wire elements of the stranded conductor are concentrically twisted in layers in the same direction at the same pitch, and the stranded conductor is compressed into a circular cross-section in such a manner that a space factor of the cross-section of the conductor is not less than 99%. The present invention also provides a multi-layer compressed concentric stranded conductor which enables a uniform compression of a base stranded wire. Not more than 61 wire elements of the same diameter are twisted together in such a manner that the number of the wire elements of a Nth layer except for the central wire element is 6N and that a line, interconnecting the centers of the wire elements of each of those layers including a second layer and any other layer outside of the second layer counting from the central wire element, has a dodecagonal shape, and subsequently the thus twisted wire elements are compressed into a circular cross-sectional shape.
