摘要
近年来,稀土冠醚配合物的研究受到广泛重视,但稀土溴化物冠醚配合物的报道甚少。
The Solubility of the ternary syslem,YBr3. 3H2O-l8C6 - C2H5OH,at 25℃ has been investigated by the modified semimicro method for study of phase eguilibrium . The refractive indexes of saturated solutions have been determined . The results indicated that there is one coordination compound formed in this system at 25℃ : YB3 18C6 · 3H2O. Examination of the role played by water in this system during equilibrium showed that the mole ratio of H2O to YBrs always equals to 3:1,no matter it is in liquid or solid phare. The chemical analytical results shanv that the diried samples have the compositions ,YBr, · 18C6 · 3H2O and YBr3 · 18C6.
