Ammonium Chloride Solubility Measurement, Molecular Simulation, and Correlation in Binary Solvents from 283.15 to 323.15 K
The solubility of ammonium chloride in water + methanol/ethanol/1-propanol/isopropanol binary solvent systems was determined by the gravimetric method at atmospheric pressure. The temperature was varied from 283.15 to 323.15 K. Within this temperature range, solubility increased with temperature. The mole fraction solubility in the binary solvent systems followed this order: water + methanol > water + ethanol > water + 1-propanol > water + isopropanol. Molecular electrostatic potential analysis and reduced density gradient (RDG) plot analysis were used to study the intermolecular interactions. The solubility data were correlated using the modified Apelblat equation, the van’t Hoff equation, the λh equation, and the Jouyban–Acree model. Understanding these solubility behaviors is essential for designing crystallization and purification processes for ammonium chloride.
