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

摘要/Abstract

摘要：

在25~60 ℃的条件下,采用静态法测定了AlCl₃·6H₂O在FeCl₃-CaCl₂-HCl-H₂O体系中的溶解度。同时以OLI软件为平台,采用Bromley-Zemaitis活度系数模型预测了该温度范围内AlCl₃·6H₂O在FeCl₃-CaCl₂-HCl-H₂O体系中的溶解度,并将实验和预测结果做了对比。结果表明,在FeCl₃-HCl-H₂O和CaCl₂-HCl-H₂O这2个体系中,温度对AlCl₃·6H₂O溶解度的影响均可忽略;在相同温度和盐酸浓度下,随着FeCl₃和CaCl₂浓度的增大,AlCl₃·6H₂O的溶解度均减小;在相同温度、相同FeCl₃和CaCl₂浓度下,盐酸浓度对AlCl₃·6H₂O在2个体系中溶解度的影响均显著,随着盐酸浓度的增大,AlCl₃·6H₂O的溶解度急剧减小。比较后发现,实验数据和模型预测值吻合良好。

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
