本文用热分析方法探讨了在不同水蒸气分压下LaCl_3·7H_2O的脱水过程,首次得到了基本分离的LaCl_3·2H_2O,并确定了它的存在条件,同时还发现并制备了尚未见报道的LaCl_3·5H_2O。
In this paper, the dehydration process of LaCl_3 · 7H_2O under different partial pressures of water vapor was investigated by means of thermal analysis, and the basic separation of LaCl_3 · 2H_2O was obtained for the first time. The existence conditions of LaCl_3 · 2H_2O were also determined. At the same time, LaCl_3 5H_2O.
