发明名称 VERFAHREN ZUR HERSTELLUNG VON DICARBONSÄUREN
摘要 <p>A process of the present invention produces a corresponding dicarboxylic acid by oxidative cleavage of a cycloalkane with oxygen and performs a reaction in the presence of a catalyst including an imide compound and a metallic compound, the imide compound having a cyclic imide skeleton represented by following Formula (I): <CHEM> wherein X is an oxygen atom or an-OR group, and wherein R is a hydrogen atom or a hydroxyl-protecting group, under conditions of a reaction temperature of 80 DEG C or higher and a concentration of the cycloalkane in a system of 21% by weight or more. The imide compound includes, for example, N-hydroxyphthalimide. The amount of the imide compound is, for example, from about 0.000001 to about 0.01 mole per mole of the cycloalkane. In the production of a corresponding dicarboxylic acid by catalytic oxidation of a cycloalkane with oxygen, the present invention can yield the dicarboxylic acid in a high space time yield even using a small amount of the catalyst.</p>
