Abstract: PROBLEM TO BE SOLVED: To provide a ketone from the corresponding secondary alcohol at a high conversion and a high selectivity. SOLUTION: This ketone compound is obtained by oxidizing the corresponding secondary alcohol having at least secondary hydroxy group in the presence of a reducing inorganic compound or acid, with bromic acid or its salt, at >=40 deg.C to convert the secondary hydroxy group to oxo group. The ratio of the bromic acid or its salt is less than 1 chemical equivalent based on the secondary hydroxy group and the ratio of the reducing inorganic compound or acid is 0.01-0.9 chemical equivalent based on the bromic acid. When a polyhydric alcohol having a secondary hydroxy group and a primary hydroxy group (propylene glycol, glycerol or the like) is used as the alcohol, the corresponding hydroxyketone compound is produced. A sulfite, a hydrogensulfite, a pyrosulfite, a thiosulfate or the like can be used as the reducing inorganic compound.

Abstract: PROBLEM TO BE SOLVED: To obtain a transparent film stably retaining a rare earth complex. SOLUTION: This film is obtained from a polymer-rare earth complex comprising a rare earth element as a central metal and a polymeric compound as a ligand, wherein the polymeric compound is obtained by bonding bipyridyl, phenanthroline and their derivatives, all of which have a site located by conjugated π-electrons, to the main chain of a polymer to form a pendant-shape. The method for producing the film from the polymer-rare earth complex comprises coating a base with a solution dissolving the polymeric compound in an organic solvent to previously form a film, impregnating the formed film with an organic solvent containing a rare earth ion, then drying the impregnated film, wherein the polymeric compound is obtained by bonding bipyridyl, phenanthroline and their derivatives, all of which have the site located by conjugated π-electrons, to the main chain of the polymer to form the pendant-shape.

Abstract: PROBLEM TO BE SOLVED: To obtain a catalyst carrier capable of holding high catalytic activity for a long period of time. SOLUTION: A catalyst carrier is constituted of a polymer having a structural unit represented by formula (wherein n is a positive integer and a quinoline ring may have a substituent other than a substituent shown in the formula). A metal complex catalyst having long catalytic life and excellent in heat resistance is obtained by coordinating a metal compd., for example, cuppric chloride with the pyridyl site of the catalyst carrier.

Abstract: PROBLEM TO BE SOLVED: To provide a method for suppressing decomposition of a ketal or an acetal and a method for manufacturing the ketal or the acetal while suppressing decomposition thereof.
SOLUTION: The decomposition of the ketal or the acetal derived from an α-hydroxyketone compound or an α-hydroxyaldehyde compound is suppressed by causing a base to be present. In the manufacture of the ketal or the acetal derived from the α-hydroxyketone compound or the α-hydroxyaldehyde compound, a post-treatment step after the reaction is carried out in the presence of the base.

Abstract: PROBLEM TO BE SOLVED: To maintain high catalytic activity over a long period of time by using a metallic complex catalyst obtained by coordinating a metallic compound to the bipyridyl part of a carrier for a catalyst comprising a specified polymer. SOLUTION: The carrier for a catalyst comprises a polymer having a structural unit of the formula [where R1 and R2 are the same or different and are each H, a hydrocarbon, a halogen or an alkoxy and (n) is an integer of >=2, e.g. 2-100]. A metallic compound is coordinated to the bipyridyl part of the carrier to obtain the objective metallic complex catalyst. Cupric chloride or a halide of a metal such as ruthenium or rhodium is, e.g. used as the metallic compound. The metallic complex catalyst is obtained by allowing the metallic compound to react with the carrier in an appropriate solvent. The complex formation reaction is carried out, e.g. in an inert gaseous atmosphere of nitrogen or argon or in an atmosphere of carbon nonoxide under atmospheric pressure or elevated pressure.

Abstract: PROBLEM TO BE SOLVED: To obtain a carrier for an oxidation catalyst capable of retaining a high catalyst activity for a long time. SOLUTION: A carrier for a catalyst comprises a compound having a structural unit of poly(2,2'-bipyridine-5,5'-dyl) represented by the formula, wherein n represents an integer of 2 or larger). A metal compound, e.g. copper(II) chloride, is coordinated on a bipyridyl position of the carrier for catalyst so as to obtain a metal complex catalyst having a long catalyst life and excellent in heat resistance. Particularly, even if the metal compound is a metal halide, corrosion of a reaction device caused by a halide ion is reduced largely.
