The solubilities refraction indices and densities of the saturated solutions of the titled quaternary systems at 25 ℃ have been investigated for the first time and thier solubility diagrams, property diagrams hare been constructed.
In the solubility diagrams, there are five crystallization regions corresponding to KCl,MgCl2-6H2O, CO(NH2)2, MgCl2.4CO(NH2)2-2HaO and MgCl2•CO(NH2)2•4H2O, respectively for KCl-MgCl2-CO(NH2)2-H2O system, four crystallization regions corresponding t0 K2SO4,MgSO4•7H2O, CO(NH2)2 and K2SO4.MgSO4•6H2O, respectively for system K2SO4-MgSO4-CO(NH2 )2-H2 O system.
