Herein, a fiber-supported imidazolium-based ionic liquid catalyst in impellers of the agitation system was developed for efficient cycloaddition of CO2 with epoxides under metal- and solvent-free conditions. The fiber-supported ionic liquid catalyst was designed collectively and synthesized systematically, and it was characterized in detail on the physicochemical properties via various technologies during both the preparation and utilization processes. Moreover, the influence of ionic liquid structures and reaction conditions on the cycloaddition was inspected, and the fiber catalyst-mediated CO2 conversion proceeded smoothly (100 °C and 1 MPa) in a gram-scale for the synthesis of organic carbonates in good to quantitative yields. Notably, the novel fiber catalyst in impellers of the agitation system also displayed prominent recyclability (21 cycles), and the protocol could be operated concisely with a good prospect for industrial applications.

搅拌系统叶轮中纤维支撑的离子液体催化剂将CO 2转化为有机碳酸酯

本文中,开发了在搅拌系统的叶轮中的纤维负载的咪唑基离子液体催化剂,用于在无金属和无溶剂条件下有效地将环氧化物与CO 2进行环加成反应。对纤维负载的离子液体催化剂进行了总体设计和系统的合成,并在制备和利用过程中通过各种技术对其理化性质进行了详细的表征。此外,考察了离子液体结构和反应条件对环加成反应的影响,并研究了纤维催化剂介导的CO 2转化过程顺利进行(100°C和1 MPa),以克为单位,以高至定量的产率合成有机碳酸盐。值得注意的是,搅拌系统的叶轮中的新型纤维催化剂还显示出显着的可回收性(21个循环),并且该协议可以简洁地操作,具有工业应用的良好前景。
