摘    要:研究了BiCl3-HCl-H2O系蒸发过程馏余物的物相,结果表明:馏余物物相随蒸馏温度的不同而不同,较低温度下蒸发馏余物物相除BiCl3以外还存在BiCl3·xHCl,而较高温度下蒸发馏余物中存在BiCl3和BiOCl两种物相。并探讨了形成不同馏余物物相的原因。

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.
