摘要

本文合成了3种不同烷基链长的咪唑类离子液体1-甲基-3-n-十四烷基咪唑氯([C14MIM]Cl)、1-正丁基-3-正丁基咪唑氯([C4BIM]Cl)和1-正丁基-3-n-十四烷基咪唑氯([C14BIM]Cl),并通过红外、1H-NMR和13C-NMR NMR、核磁共振和质谱对其进行了表征。考察了氯烷基化合物和咪唑化合物的结构对合成收率的影响。此外,还考察了反应温度、反应时间、反应物的摩尔比等条件对合成收率的影响,以寻找合适的合成工艺条件。

Synthesis of some imidazolium based ionic liquids and influence of some factors on reaction yields
In this paper, three imidazolium ionic liquids 1-methyl -3-n-tetradecylimidazolium chloride ([C14MIM]Cl), 1-n-butyl -3-n-butylimidazolium chloride ([C4BIM]Cl), and 1-n-butyl-3-n-tetradecylimidazolium chloride ([C14BIM]Cl) with different alkyl chain lengths were synthesized and characterized by infrared, 1H-NMR and 13C-NMR NMR and nuclear magnetic resonance, and mass spectra. The effect of structure of alkyl chloride and imidazole compounds on the synthesis yield was evaluated. In addition, the effects of reaction conditions such as temperature, time, and molar ratio of reactants on the synthesis yield were also investigated to find out suitable conditions for the synthesis processes.
