The rapid growth of CO2 emissions, especially from power plants, has led to the urgent need to directly capture and fix CO2 in the flue gas after simple purification rather than energy-intensive gas separation Herein, imidazolium-functionalized ionic hypercrosslinked porous polymers (HCPs) bearing adjustable surface groups were straightforwardly synthesized through co-hypercrosslinking of benzylimidazole salts and crosslinker through Friedel-Crafts alkylation. Abundant microporosity and relatively high ionic moieties were obtainable in the ethyl-group-tethered ionic HCP, giving a remarkably selective CO2 capture performance with a CO2 uptake of 3.05 mmol g-1 and an ideal adsorbed solution theory (IAST) CO2/N2 selectivity as high as 363 (273 K, 1 bar). This ionic polymer demonstrated high efficiency in the synthesis of cyclic carbonates from the coupling of various epoxides with the simulated flue gas (15% CO2 and 85% N2), giving high yields, large turnover numbers (up to 4800), and stable reusability under additive- and solvent-free conditions. In the experimental materials used by the author, we found 1,4-Bis(bromomethyl)benzene(cas: 623-24-5SDS of cas: 623-24-5)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. SDS of cas: 623-24-5 Alkyl bromides are mainly used as alkylating agents and also find application as a solvent to extract oil from seeds and wool.
