| titleOfInvention | Method of producing dimethyl ether of 2,5-thiophene dicarboxylic acid from thiophene |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a method of producing dimethyl ether of 2,5-thiophene dicarboxylic acid by reacting thiophene with carbon tetrachloride in the presence of methanol and a tris(2,4-pentanedionato)iron catalyst Fe(acac) 3 which is activated by a nitrogen-containing ligand - quinoline or pyridine, at temperature 150°C for 6 hours in molar ratio 0.04:0.4:4:45:30. Dimethyl ether of 2,5-thiophene dicarboxylic acid is used in production of electroconductive polymers, electrodes, sensors, capacitors, displays, optical brighteners, gel electrolytes and ion-exchange membranes. n EFFECT: high output of product. n 1 tbl |
