以Fe~(3+)代替Pd-C和Raney Ni为催化剂、水合肼为供氢体、3,3′-二硝基-4,4′-二氨基二苯醚为受氢体、甲醇为溶剂,进行催化转移氢化反应,产物3,3′,4,4′-四氨基二苯醚(TADPO)质量好,得率可达80%。此外,还对反应温度、时间、以及水合肼、催化剂、溶剂用量,水合肼浓度、催化剂重复使用等影响因素进行了研究,获得了较佳工艺条件。本法制得的TADPO与均苯四甲酸二酐缩聚可制得性能良好的聚眯唑吡咙。 Fe ~ (3+) instead of Pd-C and Raney Ni as a catalyst, hydrazine hydrate hydrogen donor, 3,3’-dinitro-4,4’-diaminodiphenyl ether as hydrogen, methanol Solvent for catalytic transfer hydrogenation reaction, the product 3,3 ’, 4,4’-tetra-amino diphenyl ether (TADPO) good quality, yield up to 80%. In addition, the influencing factors such as the reaction temperature and time, hydrazine hydrate, catalyst, solvent, hydrazine hydrate concentration and repeated use of catalyst were also studied. The optimum technological conditions were obtained. The TADPO prepared by this Law and pyromellitic dianhydride polycondensation can be prepared with good performance poly pyrazole pyridine throat.
