    • An object of the present invention is to provide a catalyst exhibiting excellent performance particularly in partial oxidation reaction. Another object is to provide a method for efficiently producing carboxylic acid or carboxylic anhydride through vapor-phase partial oxidation of an organic compound by use of an oxygen-containing gas in the presence of the catalyst. The catalyst contains (1) diamond; (2) at least one species selected from among Group 5 transition element oxides, collectively called oxide A; and (3) at least one species selected from among Group 4 transition element oxides, collectively called oxide B. The method for producing a carboxylic acid or a carboxylic anhydride includes subjecting an organic compound to vapor phase partial oxidation by use of an oxygen-containing gas in the presence of the catalyst, wherein the organic compound is an aromatic compound having one or more substituents in a molecule thereof, the substituents each including a carbon atom bonded to an aromatic ring.
    • 本发明的一个目的是提供一种催化剂具有特别在部分氧化反应的优异性能。 另一个目的是提供一种通过有机化合物的气相部分氧化通过在催化剂的存在下使用含氧气的气体有效地生产羧酸或羧酸酐的方法。 该催化剂含有(1)金刚石; (2)从第5族过渡元素的氧化物,统称氧化物A中选择的至少一种物质; 和(3)从第4族过渡元素的氧化物中选择的至少一种物质,统称氧化物B.用于制造羧酸或羧酸酐的方法,包括:通过使用经受有机化合物气相部分氧化的含氧 在催化剂的存在下,worin有机化合物气体是在分子中具有一个或多个取代其的芳香族化合物,均包括在芳环键合到碳原子上的取代基。
