Abstract
A series of ionic polymers (DipyBr, n = 2, 3, 4) have been synthesized under solvothermal conditions using diaminodibenzo-18-crown-6, 4-pyridinecarboxaldehyde and the corresponding bromomethyl monomer in one-pot through multi-components reactions. After comprehensive characterization of these ionic polymers by FT-IR, SEM, TGA, C CP MAS NMR, XPS, N adsorption isotherm, etc., the performance of CO fixation reaction and iodine vapor adsorption were deliberated in details. Notably, the DipyBr catalyst exhibited the best conversion yield of 97.6% for CO fixation at the controlled conditions, and the preliminary kinetic study indicated that the activation energy () for CO cycloaddition reaction catalyzed by DipyBr was determined as 70.66 kJ·mol. Furthermore, the study of iodine vapor capture showed that DipyBr has a high iodine absorption capacity (5171 mg·g).
利用二氨基二苯并-18-冠醚-6，4-吡啶甲醛和相应的溴甲基单体，通过多组分反应，在溶热条件下合成了一系列离子聚合物（DipyBr，n = 2，3，4）。通过傅立叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）、热重分析（TGA）、C CP MAS 核磁共振（NMR）、XPS、氮吸附等温线等对这些离子聚合物进行综合表征后，详细讨论了它们在 CO 固定反应和碘蒸气吸附方面的性能。初步的动力学研究表明，DipyBr 催化 CO 环加成反应的活化能（）为 70.66 kJ-mol。此外，碘蒸气捕获研究表明，DipyBr 具有很高的碘吸收能力（5171 mg-g）。
期刊介绍：
Journal of Industrial and Engineering Chemistry is published monthly in English by the Korean Society of Industrial and Engineering Chemistry. JIEC brings together multidisciplinary interests in one journal and is to disseminate information on all aspects of research and development in industrial and engineering chemistry. Contributions in the form of research articles, short communications, notes and reviews are considered for publication. The editors welcome original contributions that have not been and are not to be published elsewhere. Instruction to authors and a manuscript submissions form are printed at the end of each issue. Bulk reprints of individual articles can be ordered. This publication is partially supported by Korea Research Foundation and the Korean Federation of Science and Technology Societies.
