| 摘 要： | 离子液体因其溶解能力良好,物理、化学性质稳定,沸点高,难挥发,不会造成二次污染等诸多优点,成为了21世纪最有前景的绿色溶剂之一。将己内酰胺-四丁基氟化铵离子液体配置成不同浓度的水溶液,测定其表面张力。结果表明,该离子液体的表面张力随温度的升高而降低,随离子液体浓度的增加而减小;在一定浓度的时候,离子液体的表面张力小于水的表面张力。

| Abstract: | Ionic liquid is one of the most important potential green solvents in 21st century because of its many advantages, such as good dissolving capacity and physical and chemical properties, high boiling point, less volatile, and without sencondary pollutions. Different concentrations of eaprolaetam - tetrabutylammonium fluoride ionic liquid aqueous solutions were prepared, the surface tensionse of which were measured. The results showed that the surface tensions of the ionic liquids decreased with increase of temperature and the ionic liquid concentration;the surface tension of the pure ionic liquid was smaller than that of water at certain ionic liquid concentration. |
