ASSESSMENT AND OPTIMIZATION OF THE PHASE DIAGRAMS AND THERMODYNAMIC DATA OF SOME BINARY SYSTEMS CONTAINING PRASEODYMIUM CHLORIDES

In this paper a critical assessment and optimization of the phase diagrams and thermodynamic properties of the PrCl_3-MCl(M=Li,Na)and PrCl_3-MCl_2(M=Mg,Ca,Sr,Ba) binary systems have been per- formed.The assessed and optimized binary phase diagrams and thermodynamic data with self consistency are a better basis for constructing multicomponent phase diagrams.

核磁共振法测绘相图 Ⅰ.PrCl_3-CH_3CONH_2-D_2O体系

本文用~1HNMR方法,利用带同轴毛细管的样品管,测定了PrCl_3CH_3CONH_2-D_2O体系的三元等温相图。利用化学位移及积分面积比求得平衡体系中液相及固相的组成。核磁共振方法具有快速、准确、样品用量少的特点。
