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。
In this paper, the ternary isothermal phase diagram of PrCl_3CH_3CONH_2-D_2O system was determined by ~ 1HNMR method using a sample tube with coaxial capillaries. The composition of liquid phase and solid phase in the equilibrium system was calculated by chemical shift and integral area ratio. The method of NMR has the characteristics of fast, accurate, less sample usage.
