発明の名称 (英語) METHOD FOR PRODUCING OXIDE USING β-MANGANESE DIOXIDE 新技術説明会
発明の概要(英語) Provided for the purpose of efficient oxide production is a method for producing an oxide by oxidation of a starting compound in the presence of oxygen, characterized in that the starting compound is oxidized in the presence of manganese dioxide having a β-type crystal structure.
従来技術、競合技術の概要(英語) BACKGROUND ART
Lignocellulosic biomass that can be reproduced such as triglycerides, crude oil, coal, natural gas or the like non-renewable fossil resources and have garnered a great deal of attention as an alternative. From such biomass, biofuel, commodity chemicals, bio-plastic such as high value-added product variety can be produced. Polyethylene terephthalate (PET) polyethylene furano benzoate (PEF) are analogs of, gas barrier properties, high thermal stability, low temperature molding or the like having excellent characteristics of the recyclable biomass-derived polymer. The PEF, bottles, food packaging, such as an electronic material can be applied to a wide range of products, market in the near future are expected to grow larger.
Is the most important materials for the manufacture of a PEF, biomass-derived chemical (FDCA) in furandicarboxylic acid 2,5-. FDCA is, the presence of a catalyst, 5-by oxidizing (HMF) hydroxymethylfurfural obtained. In this case, the catalyst is used, a number previously has been reported, for example, cobalt acetate (Patent Document 1), manganese acetate (Patent Document 1), ruthenium, cobalt and cerium catalyst (Patent Document 2) as a main component and the like have been reported. In addition, recently, the inventors of the present invention, activated manganese dioxide as a catalyst efficiently from HMF FDCA method for producing a report (Non-Patent Document 1) and, in the manufacture of manganese dioxide is a highly active catalyst as FDCA has attracted attention.
Manganese dioxide, can be a plurality of crystal structure, α-type (α-MnO2), β (β-MnO2) type, γ type (γ-MnO2), δ (δ-MnO2) type, ε (ε-MnO2) type, λ-type crystal structure such as (λ-MnO2) has been known. Of these, as a method of manufacturing β-MnO2, so as to decompose the manganese nitrate is heated in an autoclave (non-patent document 2), an aqueous solution containing manganese ion as the supercritical state or a supercritical state, a method of depositing manganese dioxide (Patent Document 3), α type manganese dioxide was immersed in an acetone solution of, and the like (Patent Document 4) a method of heating have been reported.
