以1-甲基咪唑为原料, 制备了6个常规离子液体: 1-正丁基-3-甲基咪唑四氟硼酸盐及六氟磷酸盐(简称[bmim][BF4]及[bmim][PF6])、1-正己基-3-甲基咪唑四氟硼酸盐及六氟磷酸盐(简称[hmim][BF4]及[hmim][PF6])、1-正十六烷基-3-甲基咪唑四氟硼酸盐及六氟磷酸盐(简称[C16mim][BF4]及[C16mim][PF6])和4个功能化离子液体: 1-(2-羟乙基)-3-甲基咪唑四氟硼酸盐及六氟磷酸盐(简称[2-hemim][BF4]及[2-hemim][PF6])、1-乙氧羰基甲基-3-甲基咪唑四氟硼酸盐及六氟磷酸盐(简称[eocmmim][BF4]及[eocmmim][PF6]). 研究了这两类离子液体的一些物理性能, 旨在挖掘离子液体在香料香精化妆品工业中的应用价值. 分别检测了它们与一般溶剂的互溶性, 并测定了它们的表面张力和发泡性能, 实验结果表明, 仅[C16mim][BF4]和[C16mim][PF6]具有发泡性能, 发泡力分别为68和120 mm.

Using 1-methylimidazole as a starting material, six conventional and four functionalized ionic liquids have been prepared, which were 1-butyl-3-methylimidazolium tetrafluoroborate and hexafluorophosphate ([bmim][BF4] and [bmim][PF6]), 1-hexyl-3-methylimidazolium tetrafluoroborate and hexafluorophosphate ([hmim][BF4] and [hmim][PF6]), 1-hexadecyl-3-methylimidazolium tetrafluoroborate and hexafluorophosphate ([C16mim][BF4] and [C16mim][PF6]), 1-(2-hydroxyethyl)-3-methylimidazolium tetrafluoroborate and hexafluorophosphate ([2-hemim][BF4] and [2-hemim][PF6]), 1-ethoxycarbonylmethyl- 3-methylimidazolium tetrafluoroborate and hexafluorophosphate ([eocmmim][BF4] and [eocmmim][PF6]). In order to develop the application to perfume and aroma cosmetics, physical properties of these ionic liquids have been studied. Their solubilities in various organic solvents were determined and discussed, and their surface tension and foaming capabilities were also determined. The results show that only [C16mim][BF4] and [C16mim][PF6] are of foaming capability, which is 68 and 120 mm individually.

Key words: ionic liquid, functionalized ionic liquid, preparation, surface active agent
