摘　　要：对合成噻吩-2,5-二羧酸的各种路线研究,以及对各种路线所得合成噻吩-2,5-二羧酸进行分析应用,确定了以己二酸和氯气为原料的工艺路线。该路线成本低,工艺简单,需要设备少,合成的产物品质好,收率高,污染少,更容易实现工业化生产。By reaching of synthetic route of 2,5 - thiophenedicarboxylic acid and using of synthetic 2,5 - thiophenedicarboxylic acid, 2,5 -thiophenedicarboxylic acid was prepared by adipate and chlorine. The actual cost of this route was low and the less polluting materials were given off. The optimum conditions were determined. The yield was high.
