| titleOfInvention | Method for producing 3,4-dioxythiophene |
| abstract | The problem to be solved by the present invention is to provide an industrially advantageous method for 3,4-dioxythiophene useful as a raw material for polyethylenedioxythiophene. A thiodiacetic acid diester and an oxalic acid diester are reacted, After reacting with a dihaloalkane in the presence of a polyhydric alcohol or a multimer thereof to give 3,4-alkylenedioxythiophene dicarboxylic acid ester, In the presence of a basic substance, 3,4-alkylenedioxythiophene dicarboxylic acid ester is converted to 3,4-alkylenedioxythiophene dicarboxylic acid, Provided is a production method in which a decarboxylation reaction is carried out in a polyhydric alcohol in the presence of a metal catalyst, followed by distillation under reduced pressure to produce 3,4-dioxythiophene. [Selection figure] None |
