Abstract: Phase equilibrium of the SbCl3-HCl-H2O system and the temperature effect on the distillation rate of As and recovery of Sb in distillation process have been studied. The phase diagramsof temperature-concentration and Y-X (Y : composition of gaseous phase , X : compostion of liq-uid phase) diagrams of the SbCl3-HCl-H2O system with 4 , 8 , 12 mol/L HCl have experimentally been measured. From the results obtained.a rectification method to prepare high purity SbCl3 from aqueous solution has been proposed.
