Here we demonstrate the deep removal of SO2 with high uptake capacity (1.55 mmol g-1) and record SO2/CO2 selectivity (>5000) at ultra-low pressure of 0.002 bar, using ionic ultramicroporous polymers (IUPs) with high d. of basic anions. The successful construction of uniform ultramicropores via polymerizing ionic monomers into IUPs enables the fully exploitation of the selective anionic sites. Notably, the aperture size and surface chem. of IUPs can be finely tuned by adjusting the branched structure of ionic monomers, which play critical roles in excluding CH4 and N2, as well as reducing the coadsorption of CO2. The swelling property of IUPs with adsorption of SO2 contributed to the high SO2 uptake capacity and high separation selectivity. Systematic investigations including static gas adsorption, dynamic breakthrough experiments, stability tests and modeling studies confirmed the efficient performance of IUPs for trace SO2 capture. The results came from multiple reactions, including the reaction of 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Safety of 1,4-Bis(bromomethyl)benzene)
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. Due to the reactivity of bromide, they are used as potential precursors or important intermediates in organic synthesis. Safety of 1,4-Bis(bromomethyl)benzene
