Hu, Qing-Hua; Jiang, Wei; Liang, Ru-Ping; Lin, Sen; Qiu, Jian-Ding published an article in 2021. The article was titled 《Synthesis of imidazolium-based cationic organic polymer for highly efficient and selective removal of ReO-4/TcO-4》, and you may find the article in Chemical Engineering Journal (Amsterdam, Netherlands).HPLC of Formula: 623-24-5 The information in the text is summarized as follows:
Rational design of anion-scavenging materials with high selectivity and stability under high acid/base extreme conditions for removing 99TcO4- is still a significant challenge. Herein, we put forward an anion exchange strategy that utilized an imidazolium-based cationic organic polymer (named ImCOP) for efficient capture of perrhenate (ReO4-), a surrogate for TcO4- with nonradioactive. ImCOP was synthesized via the quaternization reaction using tris (4-(1H-imidazol-1-yl) phenyl) amine, a tripodal flexible ligand, and 1,4-bis (bromomethyl) benzene to forming a semi-rigid structure. ImCOP exhibited high chem. stability even under 3 M HNO3 and 3 M NaOH, which was superior to those of most materials. Attributed to the charged imidazolium moieties and tertiary amine groups that produced rich adsorption sites, ImCOP can produce electrostatic interactions with ReO4-, thereby leading to a record uptake capability (1162 mg g-1) of ReO4-. Furthermore, ImCOP exhibited high selectivity for removing ReO4- in the presence of large excess of competitive anions, which was attributed to the hydrophobic surface of ImCOP. These excellent features endowed ImCOP successfully separated ReO4- from simulated Hanford waste with a high adsorption removal of 93.4%. The excellent performance suggested ImCOP would be a promising material for TcO4-/ReO4-removal, which provided a feasible pathway for designing a high-efficiency and durable material for nuclear-related environmental remediation. The results came from multiple reactions, including the reaction of 1,4-Bis(bromomethyl)benzene(cas: 623-24-5HPLC of Formula: 623-24-5)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. HPLC of Formula: 623-24-5 Dehydrobromination, Grignard reactions, reductive coupling, Wittig reaction, and several nucleophilic substitution reactions are some of the principal reactions which involve organic bromides.
