| titleOfInvention | Nitrogen-containing cyclodextrin polymer porous material and preparation method and application thereof |
| abstract | The invention discloses a nitrogen-containing cyclodextrin polymer porous material and a preparation method and application thereof. Adding 15mmol of beta-cyclodextrin into 100-150 mL of organic solvent containing 54mmol of alkali under the inert gas atmosphere, fully stirring and dissolving to obtain a solution 1, placing the solution 1 in an ice-water bath, dropwise adding 50mL of a solution 2 into the solution 1, and reacting at the temperature of 0-5 ℃ for 12 hours to obtain a reaction solution 1; dissolving 7.5mmol of polyethyleneimine into 50-75 mL of organic solvent to obtain a solution 3, dropwise adding the solution 3 into the reaction solution 1, heating to 80-100 ℃, and continuing to react for 12-24 hours to obtain a reaction solution 2; and cooling the reaction liquid 2 to room temperature, filtering, washing solid powder obtained by filtering, and drying to obtain the nitrogen-containing cyclodextrin polymer porous material. The preparation method is simple and low in cost, and the obtained material can realize CO by utilizing hydroxyl of cyclodextrin and nitrogen-containing functional groups of organic amine 2 High adsorption capacity and selectivity, large adsorption capacity, high selectivity, easy regeneration and the like. |
