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.
