摘要
研究了ＣｓＢｒ与ＲＥＢｒ＿３（ＲＥ＝Ｌａ，Ｐｒ）在氢溴酸介质中反应的四元体系的相化学关系发现了５ＣｓＢｒ·２ＲＥＢｒ＿３·２２Ｈ＿２Ｏ型化合物。以相化学关系和热分析等结果，揭示了轻稀土化合物的相似性。同时，设计了新的固相反应，合成了新类型化合物，发展了Ｍｅｙｅｒ合成方法．
Phase chemistry relation of quaternary system that CsBr and REBr_3(RE =La.Pr,Nd,Sm)react in hydrobromic acid is studied,and a new kind of compounds 5CsBr·2REBr_3.22H_2O are dis-covered and obtained.By comparing the phase chemical behavior and the results of thermal analysis,the similarity of the light rare earth compound and'bicomponent effect'is discovered.New solid re-actions are designed and new compounds synthized according to the design at the same time,Meyer'ssynthetic reaction has been developed。
