    Abstract: A method of producing Ethyl(3R,5S,6E)-7-[2-cyclopropyl-4-(4-fluorophenyl)quinoline-3-yl]-3,5-dihydroxy-6-heptenoate by means of liquid chromatography using a packing material comprising a carrier and, carried thereon, a polysaccharide derivative, wherein a part or all of the hydrogen atoms of hydroxyl and amino groups of the polysaccharide derivative are substituted with one or more substituents, such as a carbamoyl group wherein one hydrogen atom is substituted with an aromatic group having a specific alkyl group. The method allows the production of the above (3R,5S,6E) isomer with enhanced productivity to a conventional method.

    Abstract: An optically active dihydroxyheptenoic acid ester having an aromatic group is separated from a solution containing a mixture of optical isomers of digydroxyheptenoic acid ester by liquid chromatography with a packing material constituted of a carrier and a polysaccharide derivative carried on the carrier. The polysaccharide derivative is a polysaccharide in which the hydrogen atoms constituting the hydroxyl and amino groups are partially or all replaced by one or more kinds of groups selected from among carbamoyl groups monosubstituted with aromatic groups having specific alkyl groups and benzoyl groups having specific alkyl groups. According to the invention, optically active dihydroxyheptenoic acid esters can be separated more distinctly.

    Abstract: An oil immersed electrical apparatus such as an oil immersed transformer that can detect copper sulfide precipitated on coil insulating paper is provided. In the oil immersed transformer in which a coil with its surface covered by insulating paper is arranged in a container filled with insulating oil, a detection member is prepared by providing two electrodes on a surface of a plate-like pressboard formed of cellulose, which is a same material as that of the insulating paper, this detection member is arranged in contact with the insulating oil, and generation of copper sulfide is detected from reduction in a surface resistance between the electrodes. The temperature of the detection member is set higher than the temperature of the coil so that copper sulfide is generated thereon prior to generation of copper sulfide on a coil unit.
