AlCl3·6H2O在FeCl3-CaCl2-HCl-H2O体系中溶解度的模拟和测定

Abstract

Abstract:

The solubility of AlCl₃·6H₂O在FeCl₃-CaCl₂-HCl-H₂O system was determined by static method at a temperature of 25~60 ℃.Meanwhile,the solubility of AlCl₃·6H₂O in FeCl₃-CaCl₂-HCl-H₂O system within the temperature range was predicted by using the Bromley-Zemaitis activity co-efficient model embedded in the software on the platform of OLI,and the experimental results were compared with the simulated results.The results showed that in FeCl₃-HCl-H₂O and CaCl₂-HCl-H₂O systems,temperature had little influence on the solubility of AlCl₃·6H₂O and could be ignored in the two system.The solubility of AlCl₃·6H₂O decreased obviously with the increase of iron chloride and calcium chloride concentrations in the two systems.At the same temperature and the same concentration of FeCl₃ and CaCl₂,the concentration of hydrochloric acid had a significant effect on the solubility of AlCl₃·6H₂O in the two systems.The solubility of AlCl₃·6H₂O decreases sharply with the increase of hydrochloric acid concentration.It was found that the results were in good agreement by comparing the experimental data with the predicted values of the model.

Key words: AlCl₃·6H₂O, solubility, static method, Bromley-Zemaitis activity coefficient model
