摘　　要：对离子液体[emim]Ac的密度和电导率进行了实验测定与理论模型关联。结果表明,离子液体[emim]Ac的密度随温度的升高逐渐减小,当温度范围为298.15～338.15 K时,[emim]Ac的密度值变化范围为1 072～1 024 kg/m^3;离子液体[emim]Ac的电导率随温度的升高逐渐增大,当温度范围为298.15～338.15 K时,[emim]Ac的电导率值变化范围为0.369～0.983 S/m;通过比较离子液体[emim]Ac密度及电导率的理论模型关联数据与实验测定数据,得出[emim]Ac密度及电导率的理论模型关联平均相对偏差和最大相对偏差分别为:0.82%,2.65%和1.43%,2.91%,关联结果与实验测定结果一致,故认为所选模型可用于实验数据关联。The experimental measurement of the density and conductivity of the ionic liquid [emim]Ac and correlated with the theoretical model.The results show that the density of ionic liquid [emim]Ac gradually decreases with increasing temperature,when the temperature range is 298.15~338.15 K,the density value of [emim]Ac varies from 1 072~1 024 kg/m 3;the electrical conductivity of ionic liquid [emim]Ac varies with temperature increase is gradually increased,when the temperature range is 298.15 ~338.15 K,the conductivity of [emim]Ac varies from 0.369~0.983 S/m;the data are related by comparing the theoretical model of ionic liquid [emim]Ac density and conductivity.The average relative and maximum relative deviations of the [emim]Ac density and conductivity models are:0.82%,2.65% and 1.43%,2.91%,respectively.The correlation results are consistent with the experimental results,the model can be used for experimental data correlation.
