研究四元体系CsCl-NdCl_3-13%HCl(42%HOAc)-H_2O(25℃)时的相平衡关系,绘制了相应的溶度图.两平衡体系中均有新相2∶1型及1∶1型化合物存在,为用Meyer方法合成相应的化合物提供了相化学依据.发现在所研究的体系中,盐酸溶液和醋酸溶液具有“等效介质效应”.
The phase equilibrium of quaternary system CsCl-NdCl_3-13% HCl (42% HOAc) -H_2O (25 ℃) was plotted and the corresponding solubility diagrams were plotted. Both new phase 2: 1 and 1 : 1 compound, which provides a phase chemistry basis for the synthesis of the corresponding compounds by Meyer’s method.It was found that hydrochloric acid solution and acetic acid solution have “equivalent medium effect” in the system studied.
