摘要： In a process of producing a carboxypolysaccharide by oxidizing a polysaccharide in the presence of a ruthenium compound and an oxidizing agent, the expensive ruthenium is easily and efficiently recovered. Ruthenium dissolved in a reaction mixture after the oxidation of the polysaccharide is converted, after or without being subjected to a heat. treatment, to high oxidation sate, which is then recovered by the extraction with a water-insoluble organic solvent. The recovered ruthenium is reduced to low oxidation state and reused in a subsequent production of the carboxypolysaccharide.

摘要： The present invention provides a process for producing hydrogen peroxide by reacting oxygen and hydrogen in a reaction medium catalytically using, as a catalyst, a tin-modified platinum group metal supported on a carrier. In the process using said catalyst, the presence of halogen and acid in reaction medium is unnecessary unlike the prior art methods, and hydrogen peroxide of high concentration can be produced efficiently. Thus, the present process has no restriction for reactor material as seen the prior art methods and further allows for easy purification of produced hydrogen peroxide.

摘要： This invention provides a method for high efficiency, high concentration production of hydrogen peroxide wherein oxygen and hydrogen are reacted in the reaction medium in the presence of a catalyst comprising a metallic or carrier supported platinum group metal catalyst onto which an organic halogen compound which is insoluble in water, which compound excludes compounds which contain no halogen other than fluorine, has been adsorbed or a platinum group metal catalyst supported on a carrier in which a halogenated organic compound, which compound excludes compounds that contain no halogen other than fluorine, has been adsorbed to the carrier prior to supporting the platinum group metal. Since it is not necessary for halogen ions to be present in the reaction medium as it was in the prior art, the problems of deterioration due to the dissolution of the catalyst and of corrosion of the structural materials of the reaction vessel are alleviated.
