摘　　要：以1-甲基咪唑与1-溴辛烷为主要原料,采用微波法合成1-辛基-3-甲基咪唑溴盐,再以其为中间体,进行离子交换得到1-辛基-3-甲基咪唑四氟硼酸盐离子液体。将产物进行提纯处理后,研究其对钒的萃取性能。并取样对其进行红外光谱、表面张力测试等一系列性质及结构检测。结果表明:甲基咪唑与溴辛烷及NaBF_4合成的离子液体对钒的萃取效果良好,萃取率达到80%。1-Hexyl-3-methylimidazolium bromide was synthesized from 1- methylimidazolium and bromooctane with microwave. Then it was used as intermediate to prepare 1-hexyl-3-methylimidazolium tetrafluoroborate ionic liquid by the ion exchanging. After purification, the performance of this ionic liquid was researched. The results show that the extractability of 1-hexyl-3- methylimidazolium tetraftuoroborate ionic liquid for vanadium is excellent, and the extraction rate is 80%.
