الإجراء التجريبي

3,4-Ethylenedioxy-2,5-thiophenedicarboxylic acid (460 g) and a copper powder (69 g) were added to ethylene glycol (1400 g) at room temperature. The reaction mixture was stirred under air for 30 minutes at room temperature, and air was continuously introduced into the reaction mixture. The reaction mixture was then heated at 140° C. for 8 hours. After the reaction was complete, the reaction mixture was purified using the same process as described in Example 1 to obtain 3,4-ethylenedioxythiophene (281 g, purity: 98%).
