| 摘 要： | 在微波辐射下，甲基咪唑与1-氯丁烷、四氟硼酸钠3组分一步合成得到离子液体[Bmim]BF4，结构经。HNMR，IR表征。用单因素实验法得到了适宜反应条件：微波功率225W，反应时间15min，n（1-氯丁烷）：／7,（四氟硼酸钠）：n（甲基咪唑）=1．1：1．5：1。此条件下，离子液体[Bmim]BF4的收率为92.3％。该方法后处理简单，收率高，反应时间短，且采用一步法合成，简化了工艺过程和操作步骤，有利于工业化生产。

| Abstract: | Ionic liquid [Bmim] BF4 was synthesized from 1-methyl-1H-imidazole, 1-chlorobutane and NaBF4 under microwave irradiation in a solvent free system in one step. The product was confirmed with 1H NMR and IR. The results showed the optimal reaction conditions as follows: microwave power 225 W, reaction time 15 min, n(1-chlorobutane) ∶ n(NaBF4) ∶ n(N-methylimidazolium)=1.1 ∶ 1.5 ∶ 1. The reaction afforded the product in 92.3% yield. The advantages of this process include short reaction time, simple work-up operation, low cost and easy to be scaled up. |
