摘要：

The negligible vapor pressure of ionic liquids prevents the separation of ionic liquids from other nonvolatile substances by distillation. Most distillable ionic liquids have been reported are protic ionic liquids, and the aprotic ionic liquids are still scarce. In this work, we designed and synthesized a series of unsaturated bond (C=X; X is O, N, S) based ionic liquids and some of them could be distilled at a mild condition. Moreover, [MDMF]TfO shows a high efficiency for separation of EuCl3 from the mixture of EuCl3 and NdCl3.
