  A process for producing an aromatic polycarboxylic acid in which all alkyl groups are converted into carboxyl groups in a high yield by decreasing a residual amount of an intermediate product is provided. The process comprises oxygen-oxidizing an aromatic compound having a plurality of alkyl groups (e.g., durene) in the presence of a catalyst containing a cyclic imino unit having an N—OR group (wherein R represents a hydrogen atom or a protecting group for a hydroxyl group) and a transition metal co-catalyst (e.g., a cobalt compound, a manganese compound, and a zirconium compound) under heating in a lower-temperature zone and a higher-temperature zone to produce an aromatic polycarboxylic acid in which a plurality of alkyl groups are oxidized into carboxyl groups. In an initial stage of the reaction, the reaction may be conducted in a first lower-temperature zone (a reaction temperature of 60 to 120° C. and a second lower-temperature zone (an intermediate temperature zone) (a reaction temperature of 100 to 140° C.); and then, in a latter stage of the reaction, the reaction may be conducted in a higher-temperature zone (a reaction temperature of 110 to 150° C.).

  提供一种生产芳香族多羧酸的方法，其中所有烷基转化为羧基，产率高，通过减少中间产物的残留量实现。该方法包括在低温区和高温区加热的条件下，在催化剂的存在下，将具有多个烷基的芳香化合物（例如二甲苯）进行氧气氧化，其中催化剂包含具有N-OR基团（其中R代表氢原子或羟基的保护基团）和过渡金属共催化剂（例如钴化合物、锰化合物和锆化合物）的环状亚胺单元，以产生芳香族多羧酸，其中多个烷基被氧化为羧基。在反应的初始阶段，反应可以在第一低温区（反应温度为60至120°C）和第二低温区（中间温度区）（反应温度为100至140°C）进行；然后，在反应的后期阶段，反应可以在较高温度区（反应温度为110至150°C）进行。

  A method is described for autoxidizing particular ortho-dialkyl substituted aromatic compounds using a particular type of solvent which gives rise to the formation of 3-alkanoyloxyphthalide compounds, some of which are novel. The phthalides in turn are ionically oxidized to their corresponding aromatic polycarboxylic acids. Combination of the two methods provides a means for converting ortho dialkyl substituted aromatic compounds directly to the corresponding polycarboxylic acids in higher yields and at generally lower overall temperatures and reaction conditions compared to prior art methods. Polycarboxylic acids so obtained are known to be useful in the preparation of alkyds, polyesters, and the like, and, particularly, in the formation of the corresponding acid anhydrides which are used in the preparation of organic high temperature polymers such as polyamides, polyamideimides, and polyimides.

  描述了一种使用特定类型溶剂对特定邻二烷基取代的芳香族化合物进行自氧化的方法，该方法可生成 3-烷酰氧基邻苯二甲酸盐化合物，其中一些是新型化合物。 这些邻苯二甲酸盐又被离子氧化成相应的芳香族多羧酸。 与现有技术相比，这两种方法的结合提供了一种将正交二烷基取代的芳香族化合物直接转化为相应的聚羧酸的方法，收率更高，总体温度和反应条件通常更低。 众所周知，这样得到的聚羧酸可用于制备醇酸树脂、聚酯等，特别是形成相应的酸酐，用于制备有机高温聚合物，如聚酰胺、聚酰胺酰亚胺和聚酰亚胺。
