采用一步酸碱中和法制备了一种胺型离子液体—醋酸二乙胺,测定了298.15K时,该离子液体和DMSO、丙酮以及水组成的二元溶液在全浓度范围的电导率和黏度,并采用Casteel-Amis经验公式关联了溶液电导率随浓度的变化规律.结果表明,同一体系中,溶液黏度比较小时,电导率随离子液体浓度的增加而增大,在溶液黏度比较大时,电导率随离子液体浓度的增加而减小.此外,介电常数较大的溶剂对离子液体电导率的影响更为显著.
A one-step acid-base neutralization method was used to prepare amine-type ionic liquid-diethylamine acetate. The conductivity and viscosity of the binary solution composed of the ionic liquid and DMSO, acetone and water were measured at 298.15K in the full range of concentration , And the Casteel-Amis empirical formula was used to correlate the conductivity of the solution with the change of concentration.The results show that the conductivity increases with the increase of ionic liquid concentration in the same system when the solution viscosity is relatively small, Conductivity decreased with the concentration of ionic liquid.In addition, the larger the dielectric constant of the ionic liquid conductivity more significantly.
