METHOD FOR PREPARING FORMAMIDE COMPOUNDS VIA HYDROGENATION OF CARBON DIOXIDE CATALYZED BY POROUS MATERIALS
A method for preparing formamide compounds via hydrogenation of carbon dioxide catalyzed by porous materials includes the following steps: by taking porous organometallic polymers as catalysts, reacting amine compounds with carbon dioxide and hydrogen under an air atmosphere to prepare formamide compounds. The method has the advantages of high reaction efficiency, good selectivity, mild conditions, economy, environmental protection, and simple operation. The catalysts are solid organometallic polymers with large specific surface area, strong carbon dioxide adsorption, hierarchical pore distribution, and uniformly dispersed metal centers. They are designed and synthesized as the reaction catalysts by changing the proportion of the cross-linked comonomer. The catalysts can be especially used for catalytic synthesis of fine chemical N, N-dimethylformamide (DMF) without addition of any additional solvent, alkali, or other additives, which is convenient for separation and purification of DMF.
