| Abstract: | A process for preparing 2,5dichloro3thiophene carboxylic acid is described. After reacting 2,5dichlorothiophene with acetyl chloride by using aluminum chloride as catalyst, 2,5dichloro3acetylthiophene was prepared. By the reaction of this product with sodium hypochlorite solution, 2,5dichloro3thiophene carboxylic acid was obtained. |
