摘要: 通过改进的方法合成了1-苄基-3-烷基苯并三氮唑类离子液体。 目标产物结构经FT-IR、1H NMR和13C NMR确证。 当烷基取代的苯并三氮唑、催化剂CuI和溴苄的物质的量比为10∶2.5∶11时,反应5~6 h收率可达82.7%~86.1%,探讨了离子液体溶解性及熔点与结构的关系。

Abstract: An improved procedure was developed for the synthesis of 1-benzyl-3-alkylbenzotriazolium ionic liquids from commercially available starting materials. The structures of target compounds were characterized by FT-IR, 1H NMR and 13C NMR. The yield reaches 82.7%~86.1% when the molar ratio of substituted alkyl benzotriazole to cuprous iodide and benzyl bromide is 10∶2.5∶11, and the reaction time is 5~6 h. Moreover, their solubility, the relationship between molecular structure and melting point of the ionic liquids were investigated.

Key words: benzotriazolium ionic liquids, catalysis, synthesis, characterization
