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280.7S·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287.3S·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.
The conductivity of four kinds of neodymium salts, Nd (CF3SO3) 3, Nd (ClO4) 3, Nd (NO3) 3 and NdCl3 in polar aprotic solvent DMF were investigated by conductivity measurements. The limit molar conductivities of Nd (CF3SO3) 3 and Nd (ClO4) 3 were 278.8 and 280.7S · cm2 · mol-1, respectively.The ultimate molar conductivity of Nd (NO3) 3 and NdCl3 were 297.2 and 287.3S · cm2 · mol-1, respectively. The conductivity of Nd (CF3SO3) 3 and Nd (ClO4) 3 linearly changed with the temperature in the range of 25-65 ° C. The conductance of Nd (NO3) 3 and NdCl3 Showed a clear ionic association.
