| 摘 要： | 系统研究了一种对空气和水稳定的疏水型离子液体[PP13][Tf2N]在不同有机溶剂中的电导率变化.在288.15～318.15K温度范围内,测定了离子液体[PP13][Tf2N]在乙醇或正丙醇中的电导率数据.结果表明:离子液体[PP13][Tf2N]在两种有机溶剂中的电导率都要高于纯离子液体的电导率;在乙醇中的电导率要高于在正丙醇中的电导率,而且电导率都随着离子液体浓度的增加先升高,达到极大值后降低.最后将电导率对浓度、温度分别采用Casteel-Amis经验方程,Vogel-Fulcher-Tamman方程进行拟合.

| Abstract: | The conductivity of hydrophobic [PP13][Tf2N],which is an air-and water-stable ionic liquid,in ethanol or 1propanol were conducted at different temperature to investigate the effect of different organic solvent and temperature on the conductivity.For a given concentration of ionic liqulid,the conductivity in ethanol is higher than that in 1-propanol,moreover,the conductivity of [PP13][Tf2N] in above two organic solvents initially increases and reaches to the maximum,then continues to decreases with the concentration of [PP13][Tf2N] increasing,which is consistent with the fitting results using empirical Casteel-Amis(CA) equation and VFT equation. |
