关于稀土冠醚配合物的研究近年来一直为人们所重视。但多采用直接合成的方法进行研究,采用溶剂多为乙腈或丙酮。为了考查溶剂对稀土盐与冠醚间配合行为的影响,我们用半微量相平衡方法研究了Yb(NO_3)_3·3H_2O-B15C5-C_2H_5OH三元体系在18℃时的溶解度。此外,还用其它方法对该体系中形成的配合物进行了考查。
Research on rare earth crown ether complexes has been valued by people in recent years. However, more direct synthesis methods to study the use of solvents for the most acetonitrile or acetone. To investigate the effect of solvents on the coordination behavior between rare earth salts and crown ethers, the solubility of Yb (NO_3) _3 · 3H_2O-B15C5-C_2H_5OH ternary system at 18 ℃ was studied by semi-micro phase equilibrium method. In addition, the complexes formed in this system were also examined by other methods.
