用半微量相平衡方法研究了LaCl33H2O-18C6-CH3COCH3三元体系在25℃时的溶解度,并测定了各饱和溶液的折光率。其结果表明,该体系中形成两种化学计量的配合物:2LaCl318C66H2OCH3COCH3与LaCl318C63H2O0.5CH3COCH3。制备了固态配合物,用化学分析,IR,TG-DTG和DSC研究了配合物的组成和性质。
The solubility of LaCl33H2O-18C6-CH3COCH3 ternary system at 25 ℃ was studied by semi-micro phase equilibrium method and the refractive index of each saturated solution was measured. The results showed that two stoichiometric complexes were formed in this system: 2LaCl318C66H2OCH3COCH3 and LaCl318C63H2O0.5CH3COCH3. Solid complexes were prepared and their chemical compositions, IR, TG-DTG and DSC were used to study the composition and properties of the complexes.
