摘要
离子液体因类属环保绿色溶剂而备受青睐。本研究通过微波合成法,以N-甲基咪唑和溴代烷合成[BMIM][PF6]离子液体。对产物进行红外、核磁、高效液相表征,结果表明产物同市售产品表征结果一致,产物纯度高达99.3%,表明产物即为目的产物。此离子液体的合成标志微波合成法在离子液体中合成的可行性,有望应用于废水处理过程中金属离子的萃取中去,实现离子液体的"绿色"价值。
Ionic liquids are very popular because they are environmentally friendly and green solvents.In this study,[BMIM][PF6]ionic liquids were synthesized by microwave synthesis with N-methylimidazole and bromoalkane.The product was characterized by FT-IR,1 H-NMR and HPLC analytical methods.The results showed that the product was identical with the commercial product.The purity of the product was up to 99.3%,indicating that the product was the target product.The synthesis of ionic liquids indicates the feasibility of microwave synthesis in ionic liquids,which is expected to be applied in the extraction of metal ions in wastewater treatment process and realize the "green" value of ionic liquids.
