Abstract A series of micro-mesoporous polymeric ionic liquids (PILs) have been successfully synthesized by the method of anion and cation copolymerization. Then use FT-IR, N2 adsorption-desorption isotherms, SEM, and TG to characterize them. Furthermore, the catalytic performance of the synthesized PILs was investigated for the Prins reaction of propylene with 1, 3, 5-trioxane. Among the four PILs synthesized, VIMBs-DVB-SSA has better catalytic activities for the Prins reaction. Under the optimal conditions, 100℃, 8wt%, 4h and n (propylene)/n (1, 3, 5-trioxane) =4:1, the conversion of formaldehyde (99.8%) and selectivity (81.7%) for 4-methyl-1, 3-dioxane. In addition, the effects of reaction time, catalyst dosage, and reaction temperature and mole ratio of reaction substrates on the reaction were also investigated. The prepared catalyst had good thermal stability and can be reused easily.

聚合物离子液体作为 Prins 反应的新型催化剂

摘要 采用阴阳离子共聚方法成功合成了一系列微介孔聚合物离子液体（PILs）。然后使用 FT-IR、N2 吸附-解吸等温线、SEM 和 TG 对其进行表征。此外，还研究了合成的 PIL 对丙烯与 1, 3, 5-三恶烷的 Prins 反应的催化性能。在合成的四种PILs中，VIMBs-DVB-SSA对Prins反应具有较好的催化活性。在100℃、8wt%、4h和n(丙烯)/n(1,3,5-三恶烷)=4:1的最佳条件下，4-甲醛的转化率(99.8%)和选择性(81.7%)甲基-1, 3-二恶烷。此外，还考察了反应时间、催化剂用量、反应温度和反应底物摩尔比对反应的影响。
