PHASE EQUILIBRIUM OF SBCL3-HCL-H2O SYSTEM
（Central South University of Technology; Changsha 410083 ; China）
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.
Key words: antimony trichloride hydrochloric acid phase equilibrium rectification
