| Abstract: The equilibrium solubility of KCl-ZnCl2-HCl(11%)-H2O(25℃) quaternary system at 25℃ was determined and the phase diagram was constructed. This system is complicated with two new compounds K2ZnCl4·H2O (2∶1 type) and K5Zn4Cl13·3H2O (5∶4 type) which have been obtained from the system and have been characterized by XRD, TG-DTG. The result shows that compound K5Zn4Cl13·3H2O of 5∶4 type is the new one which have not been reported before. For compound K2ZnCl4·H2O parameter of unit cell is a=11.976?, b=9.066?, c=7.015?, and it belong to orthogonal crystalline system. The result of TG-DTG shows that compounds K2ZnCl4·H2O and K5Zn4Cl13·3H2O will dehydrate at 400℃ and 670℃, respectively. |
