Solid–Liquid Phase Equilibria in the Quinary System NaCl + NaOH + Na(2)CO(3) + Na(2)SO(4) + H(2)O at 363.15 K
[Image: see text] Solid–liquid equilibria in the quinary system NaCl + NaOH + Na(2)CO(3) + Na(2)SO(4) + H(2)O at 363.15 K were measured by the wet residue method, and the equilibrium solid phases and solubilities of saturated solutions were determined experimentally. Using the experimental results,...

description | [Image: see text] Solid–liquid equilibria in the quinary system NaCl + NaOH + Na(2)CO(3) + Na(2)SO(4) + H(2)O at 363.15 K were measured by the wet residue method, and the equilibrium solid phases and solubilities of saturated solutions were determined experimentally. Using the experimental results, dry-salt phase diagrams and water diagrams versus composition diagrams were plotted (saturated with saturated sodium chloride, sodium hydroxide, sodium carbonate, and sodium sulfate). The experimental results show that there are a solid solution (γ-salt, mNa(2)SO(4)·nNa(2)CO(3)) and co-saturation complex salts (S3, Na(2)SO(4)·NaCl·NaOH and S1, NaOH·Na(2)SO(4)) formed in this quinary system. Based on Xu’s activity coefficient model, the solubilities of the quinary system NaCl + NaOH + Na(2)CO(3) + Na(2)SO(4) + H(2)O at 363.15 K were calculated with corresponding parameters. Comparing the experimental and calculated results, it was shown that the calculated values had a good agreement with the experimental ones. |
