    Abstract: A process for producing dicarboxylic acids by oxidative cleavage of cycloalkanes with oxygen, characterized in that the oxidative cleavage is conducted in the presence of a catalyst constituted of both an imido compound having a cyclic imide skeleton represented by the general formula (I): (I) [wherein X is oxygen or OR (wherein R is hydrogen or a hydroxyl-protecting group)] and a metal compound at a temperature of 80 °C or above in a reaction system having a cycloalkane concentration of 21 wt% or above. The imido compound is N-hydroxyphthalimide or the like, and is used in an amount of about 0.000001 to 0.01 mol per mol of the cycloalkane. In producing dicalboxylic acids by catalytic oxygenation of cycloalkanes, this process attains high space time yield even with a reduced amount of a catalyst.
