Versuchsvorschrift

The 2,5-diethoxycarbonyl-3,4-ethylenedioxythiophene and NaOH are mixed in the microwave reactor. The microwave reactor is heated by the 2.45 GHz microwave at a power of 500-1200 W to perform hydrolysis reaction for no more than 20 minutes to obtain 2,5-dicarboxy-3,4-ethylenedioxythiophene. The reaction is shown in the chemical formula (D).
