| titleOfInvention | Method for preparing 2, 5-furandicarboxylic acid by catalytic carbonylation |
| abstract | The invention discloses a method for preparing 2, 5-furandicarboxylic acid by catalytic carbonylation, which takes 5-bromo-2-furoic acid as a raw material, and a reaction system simultaneously containing 5-bromo-2-furoic acid, a solvent, alkali and a palladium catalyst is stirred and reacted for 4-20 hours at the temperature of 50-120 ℃ in the atmosphere of carbon monoxide; then, removing the solvent, adding an acidifying reagent to adjust the pH value to acidity, and separating out the target product 2, 5-furandicarboxylic acid; the palladium catalyst contains palladium element; the solvent is water or a mixture of water and an organic solvent. Compared with the prior art, the invention can effectively solve the problem that human grain resources are consumed for preparing the FDCA by taking the 5-bromo-2-furoic acid as the raw material and improving the whole process flow design of the preparation method and the reaction conditions and parameters (including the types and the proportions of the reaction raw materials, the reaction temperature, the reaction time and the like) of each step. |
