Previous work has proved that the preparation method of anhydrous magnesium chloride by using the thermal decomposition of the complex [HAE]Cl center dot MgCl2 center dot 6H(2)O is a potential process for commercial application. Normally, the complex [HAE]Cl center dot MgCl2 center dot 6H(2)O is synthesized by reaction crystallization of aniline hydrochloride (C6H5NH2 center dot HCl, [HAE]Cl) and bischofite (MgCl2 center dot 6H(2)O). The study on the solubility of [HAE]Cl in hydrochloric acid and various chloride salt solutions plays a significant role in the development, analysis, and engineering design for this new process. This work is a continuation of our systematic study of the solubility of [HAE]Cl in different chloride media, The solubility of [HAE]Cl in different concentrations of HCl (1.19-6.98 mol.kg(-1)), NaCl (0.5-3.8 mol.kg(-1)), CaCl2 (0.5-4.5 mol.kg(-1)), AlCl3 (0.5-2.8 mol.kg(-1)), and their mixed solutions was determined using a dynamic method in the temperature range from 288 to 348 K. With the purpose of improving AspenPlus's prediction capability, in regard to [HAE]Cl solubility data in the H-Mg-Na-Ca-Al-Cl-H2O systems at various temperatures, new model parameters were obtained via the regression of the experimental solubility of [HAE]Cl in single electrolyte solutions, such as HCl, NaCl, CaCl2, and AlCl3, under atmospheric pressure. With the newly obtained electrolyte NRTL (ENRTL) interaction parameters for [HAE]Cl-NaCl, [HAE]Cl-CaCl2, [HAE]Cl-AlCl3, and AlCl3-H2O, and default parameters for NaCl-H2O and CaCl2-H2O in AspenPlus, a self-consistent model for the system [HAE]-H-Mg-Na-Ca-Al-Cl-H2O was established with the maximum relative deviation of 4.3% between experimental and predicted solubility values.
