| Abstract: The solubilities of the ternary system,Y(ClO4)3·3H2O-B15C5-CH3OH,at 25℃ havebeen investigated by the semimicro method of phase equilibrium study.The refractive indexes ofsaturated solutions have been determined. There are three coordination compounds formed inthe system at 25℃. The compositions of the three coordination compounds arc:4Y(ClO4)3·3B15C5·12H2O·12CH3OH(Ⅰ),Y(ClO4)3·B15C5·3H2O.1·5CH3OH(Ⅱ)and Y(ClO4)3·ZB15C5·3H2O·CH3OH(Ⅲ).The coordination compounds (Ⅰ) and (Ⅱ) are solubleincongrucntly.The coordination compound(Ⅲ) has been isolated from methyl alcohol solutionand dried between 69-72℃ to give Y(ClO4)3. 2B15C5-3H2O.The properties of Y(ClO4)3·2B15C5·3H2O has been characterized by IR, conductivity measurement and X-ray diffractionanalysis. |
