摘 要: | 以吡啶和溴代正丁烷为原料采用微波法合成了中间体溴化N-丁基吡啶(BPy]Br),并通过正交试验对反应条件进行了优化。考察了原料配比、反应时间、微波功率对该反应的影响,结果表明:原料摩尔比1︰1.1时,微波功率在400 W,反应时间20 min为较佳的反应条件。中间体在微波辐射下经过离子交换合成了N-丁基吡啶四氟硼酸盐(BPy]BF4)和N-丁基吡啶六氟磷酸盐(BPy]PF6)。产物结构由IR和1HNMR确证。

Abstract: | In this paper, N-butyl pyridinium bromide (BPy]Br) as intermediate was synthesized by reaction of pyridine with 1-butyl bromide, orthogonal design method was employed to optimize conditions of the reaction.Then the effects of material ratio,reaction time and microwave power on the yield of BPy]Br were investigated,the results showed that the best reaction conditions were described as following: the molar ratio of the reaction material wasl:1.1,the power of microwave was 400 W,the reaction time was 20 min.After ion exchanging under microwave irradiation, N-butyl pyridinium tetrafluoroborate(BPy]BF4) and N-alkyl pyridinium hexafluorophosphate (BPy]PF6) were obtained. The structures of products were characterized by IR and ^1HNMR. |
