| 摘 要： | 通过电导测量研究了四种钕盐：Nd(CF3SO3)3、Nd(ClO4)3、Nd(NO3)3和NdCl3在极性非质子溶剂DMF中的电导性质.利用线性拟合方法求得在25 ℃下Nd(CF3SO3)3和Nd(ClO4)3的极限摩尔电导率分别为278.8和 280.7 S?cm2?mol－1.用间接方法求得Nd(NO3)3 与NdCl3 的极限摩尔电导率分别为297.2和287.3 S?cm2 ?mol－1.在25～65 ℃温度范围内，Nd(CF3SO3)3和Nd(ClO4)3的电导率随温度呈线性变化. Nd(NO3)3和NdCl3的电导行为表现出明显的离子缔合.

| Abstract: | Conductance measurements have been made on four neodymium salts: Nd(CF3SO3)3, Nd(ClO4)3, Nd(NO3)3 and NdCl3 dissolved in dimethylformamide. The limiting molar conductivity of Nd(CF3SO3)3 and Nd(ClO4)3 at 25 ℃ calculated by liner fit are 278.8 and 280.7 S?cm2?mol－1 respectively, those of Nd(NO3)3 and NdCl3 obtained by indirect method are 297.2 and 287.3 S?cm2?mol－1 respectively. The electrical conductivity of Nd(CF3SO3)3 and Nd(ClO4)3 increase linearly in the temperature range(25～65)℃. Significant ionic association exists in Nd(NO3)3 and NdCl3 solution. |
