Phase Equilibrium Study Of The Quinary-System NH₄Cl-MgCl₂-NH₃-CH₃OH-H₂O

This thesis is studying muiltsolvent and mixed electrolyte phase equilibrium states of the system NHUCl-MgCl2-NH3-CH3OH-H2O. In the ternary-system NH4Cl-CH3OH-H2O, we discuss the temperature effect on the solubility of ammonium chloride. In the quaternary-system NH4Cl-MgCl2-CH3OH-H2O, we discuss the effect of the quantity of magnesium chloride or different H2O/CH3OH ratio or temperature on the solubility of ammonium chloride. In the quinary-system NH4C1-MgCl2-NH3-CH3OH-H2O, we discuss the effect of different H2O/CH3OH ratio on the solubility of ammonium chloride, the effect of temperature on the solubility of ammonium chloride, the effect of Ammonia on the solubility of ammonium chloride and the effect of Ammonia on the solid categories of solution.It is important matter determining electrolyte solubility in the single solvent or muiltsolvent. It is also one of basic work of studing solution chemistry. The study of salt and mixed solvents not only enrich solution chemistry , but also possess important significance to separation preparation and purification of salt. At the same time the study is the base on which makes anhydrous magnesium chloride.
