Improved Synthesis and Characterization of 1-Benzyl-3-alkylbenzotriazolium Ionic Liquids
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.
