氯化1,3-二丙烯基-2-乙基咪唑离子液体的制备及黏度与电导率的测定

The preparation of 1,3-propenyl-2-ethyl-imidazole and its viscosity and conductivity test

以2-乙基咪唑为原料合成了一种新型结构的室温水溶性离子液体（氯化1，3-二丙烯基-2-乙基咪唑），并通过核磁共振波谱法及红外吸收光谱法对其结构进行表征，对该离子液体在25℃～55℃的黏度与电导率随温度及溶剂摩尔分数的变化进行了研究．结果表明，在一定条件下黏度随温度的升高及溶剂量的增加而减小；电导率随温度及溶剂摩尔分数的增大而增大．氯化1，3-二丙烯基-2-乙基咪唑离子液体的黏度与温度的拟合关系为η=7.61777-0.20409 t＋0.0017 t2．
