Improved porous HYPERCROSSLINKED polymer capture and conversion for CO2

摘要

Disclosure description is for manufacturing the conversion of method and carbon dioxide for a kind of hyperporous materials of capture. Process includes the steps that benzyl halide a first oneself polymerize via Friedel-Crafts reaction. The hypercrosslinked polymer obtained in the second step further adds an amine or heterocyclic compound at least one azo-cycle constituting atom. The invention further relates to material, to the process and its use in catalysis reaction, such as the conversion of epoxides of carbonate is obtained. The improved porous hypercrosslinked polymer of the salt of acquisition according to the present invention shows the high surfaces BET (BET surface area up to 926 m2/g) and strong CO2 absorptive capacities (14.5 wt%) it combines. The functionalized hypercrosslinked polymer catalysts display of nitrogen compound improves the conversion rates compared with known functionalized polystyrene material and an excellent regenerability. A kind of novel imidazole salts polymer modification shows extra high capture and ability to transform. According to the invention of the polymer of acquisition use can generate carbonate in high yield.
