반응 단계
3,4-Ethylenedioxythiophene-2,5-dicarboxylic acid (230 g) and basic copper carbonate (23 g) were added to DMF (600 g) at room temperature. While air was slowly introduced to the reaction mixture, it as heated at 120° C. for 5 hours. After cooling, the reaction mixture was purified using the same process as described in Example 1 to obtain 3,4-ethylenedioxythiophene (136 g, purity: 97%).
