摘 要: 研究了BiCl3-HCl-H2O系蒸發(fā)過程餾余物的物相，結(jié)果表明：餾余物物相隨蒸餾溫度的不同而不同，較低溫度下蒸發(fā)餾余物物相除BiCl3以外還存在BiCl3·xHCl，而較高溫度下蒸發(fā)餾余物中存在BiCl3和BiOCl兩種物相。并探討了形成不同餾余物物相的原因。

Abstract:The residue phase in the process of distillation of BiCl3-HCl-H2O system were studied in detail. Experimental results showed that the residue phase were distinctive at different temperature, namely BiCl3 and BiCl3·xHCl at lower temperature of distillation, BiCl3 and BiCl3 existed at higher temperature. The reason that distinctive phases of residue formed was also discussed.
Key words: BiCl3; HCl; distillation; residue phases
