摘　　要：基于氨基功能化聚离子液体与Zn2+的金属-配位作用,在室温下组装形成了具有Lewis酸碱位点的聚离子液体基金属配合物PIL-Zn,并研究了其催化CO_(2)与环氧氯丙烷生成氯丙烯碳酸酯的催化性能。通过酸碱位点的协同作用(Br-、Zn2+),PIL-Zn可在0.1 MPa、75℃、24 h、无需外加溶剂及助催化剂的条件下高效催化转化CO_(2),环氧氯丙烷转化率和目标产物氯丙烯碳酸酯选择性分别为95%和99%,并且在循环使用5次后依旧保持良好的催化性能。PIL-Zn在催化转化CO_(2)领域具有较好的应用潜力,为开发高性能催化剂材料提供了新的思路。Based on the metal-coordination interaction between amino functionalized poly(ionic liquid)-NH2 and Zn2+,a poly(ionic liquid)-based metal complex PIL-Zn with Lewis acid-base sites was assembled at room temperature,and its catalytic performance for the reaction of CO_(2) and epichlorohydrin to synthesize chloropropylene carbonate was studied.Through the synergistic effect of acid-base sites(Br-,Zn2+),PIL-Zn can effectively catalyze the conversion of CO_(2) under the mild conditions(0.1 MPa,75℃,24 h)in the absence of solvent and co-catalyst,the conversion of epichlorohydrin and the selectivity of the target product chloropropene carbonate are 95%and 99%respectively,and its catalytic performance keeps well after 5 recycles.PIL-Zn exhibits good application potential in the field of catalytic conversion of CO_(2),which provides a new idea for the development of high performance catalyst materials.
