合成了一种新型聚乙二醇桥联叔胺功能化离子液体PEG 800-DPIL（Cl）。它能与环己烷/异丙醇混合溶剂形成温度驱动的可逆两相体系。该两相体系用于Knoevenagel缩合反应，缩合率达99%。PEG 800-DPIL（Cl）可以简单地回收并循环使用几次。
A novel poly(ethylene glycol) bridged tertiary amine functionalized ionic liquid PEG800-DPIL(Cl) was synthesized. It can form a temperature driven reversible biphasic system with cyclohexane/isopropanol mixed solvent. This biphasic system was applied in Knoevenagel condensation up to 99%. PEG800-DPIL(Cl) could be simply recovered and recycled for several runs.
