  A method of this invention produces an aromatic carboxylic acid, by oxidizing an aromatic compound B with oxygen in the presence of a catalytic nitrogen-containing cyclic compound A to thereby yield a corresponding aromatic carboxylic acid, the aromatic compound B having one or more hydrocarbon groups alone as substituents on its aromatic ring, and the catalytic nitrogen-containing cyclic compound A having a skeleton represented by following Formula (i): wherein X represents oxygen atom or an -OR group, and wherein R represents hydrogen atom or a hydroxyl-protecting group, as a constitutive member of its ring. The method includes the step of carrying out a reaction at a concentration of the aromatic compound B in the reaction system of 3.0 percent by weight or less, while continuously feeding the catalytic nitrogen-containing cyclic compound A, the aromatic compound B, a reaction solvent, and oxygen to a reactor and continuously extracting a reaction mixture from the reactor. This method can produce aromatic carboxylic acids with industrially good productivity without the need for special reaction facilities and without undergoing many steps.

  本发明的一种生产芳香族羧酸的方法，是在催化含氮环状化合物 A 的存在下，用氧气氧化芳香族化合物 B，从而得到相应的芳香族羧酸，芳香族化合物 B 的芳香环上有一个或多个单独的烃基作为取代基，而催化含氮环状化合物 A 的骨架由下式(i)表示： 其中 X 代表氧原子或-OR 基团，以及 其中 R 代表氢原子或羟基保护基团，作为其环的构成成员。该方法包括以下步骤：在反应体系中芳香族化合物 B 的浓度为 3.0%（重量百分比）或更低时进行反应，同时将催化的含氮环状化合物 A、芳香族化合物 B、反应溶剂和氧气连续加入反应器中，并连续从反应器中提取反应混合物。这种方法不需要特殊的反应设备，也不需要经过许多步骤，就能生产出工业生产效率高的芳香族羧酸。

  It is desirable to provide a method for easily removing catalyst-derived impurities from a product of a reaction by the catalysis of a compound having a dicarboximide skeleton and thereby efficiently yielding a target compound with high purity. Disclosed is a method for producing an organic compound through a reaction of a substrate in the presence of a catalyst, the catalyst including a compound having a dicarboximide skeleton represented by following Formula (i): wherein R represents hydrogen atom or a hydroxyl-protecting group. The method includes the step of treating a reaction product with hot water so as to decompose and remove an impurity derived from the catalyst. The temperature of the hot water is preferably 100°C or higher.
