摘要
用N-甲基咪唑和氯代正丁烷反应,合成了作为室温离子液体中间体的氯化1-甲基-3-丁基咪唑。以丙酮为溶剂,用四氟硼酸钠和氯化1-甲基-3-丁基咪唑合成了四氟硼酸1-甲基-3-丁基咪唑室温离子液体。测定了离子液体的最大吸收波长,并且绘制了标准工作曲线。结果表明,在实验试剂用量范围内,离子液体在波长225 nm附近的吸光度与浓度呈线性关系,其线性相关系数为0.995。说明用紫外光谱法检测甲醇中离子液体含量简单、快速且测定结果准确可靠。
In the paper, the intermediate of RTIL, 1-methyl-3-butylimidazolium chloride was prepared by methyl-midazolium and alkyl halide. 1-methyl-3-butylimidazolium nitrate room temperate ionic liquid was synthesized in acetone by NaBF4 and 1- methyl-3-butylimidazolium chloride. The maximum absorption wave length was measured and the correlation coefficient of standard curve also reached as 225 run with the correspondence coefficient of 0. 995 in the range of reagent dosage under experimental conditions. It shows the method is simple, feasible and reliable.
