探索了聚合物负载季膦盐(PS-QPS)作为二氧化碳与环氧化物偶联反应的有效催化剂。结果表明，在5 Mpa二氧化碳、15 0℃、6 h的反应条件下，不添加有机溶剂或助催化剂，可制得高产率(98.6%)和高选择性(10 0%)的环状碳酸酯。考察了不同反应条件对催化剂性能的影响。该催化剂适用于多种环氧化物，以良好的产率生成相应的环状碳酸酯。催化剂易于回收，可重复使用5次，催化活性不会明显下降。讨论了PS-QPS催化合成环状碳酸酯的反应机理。采用热重分析(TGA)、扫描电子显微镜(SEM)和傅立叶变换红外光谱(FT-IR)对催化剂进行了表征。由于PS-QPS具有制备简单、活性和选择性高、稳定性好、成本低、可重复使用等独特的优点，被认为在二氧化碳固定应用中具有巨大的潜力。
Polymer-supported quaternary phosphonium salt (PS-QPS) was explored as effective catalyst for the coupling reaction of carbon dioxide with epoxides. The results indicated that cyclic carbonates with high yields (98.6%) and excellent selectivity (100%) could be prepared at the conditions of 5 MPa CO2, 150°C, and 6 h without the addition of organic solvents or cocatalysts. The effects of various reaction conditions on the catalytic performance were investigated in detail. The catalyst is applicable to a variety of epoxides, producing the corresponding cyclic carbonates in good yields. Furthermore, the catalyst could be recovered easily and reused for five times without loss of catalytic activity obviously. A proposed mechanism for synthesis of cyclic carbonate in the presence of PS-QPS was discussed. The catalyst was characterized by thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectrum. It is believed that PS-QPS is of great potential for CO2 fixation applications due to its unusual advantages, such as easy preparation, high activity and selectivity, stability, low cost, and reusability.
