Abstract

The solid-liquid equilibrium (SLE) of H₂O+ZnCl₂+Zn(H₂PO₂)₂ ternary system at 298, 313 and 333 K have been studied with the use of isothermal method. Solid phase compositions have been determined with Schreinemaker’s method. H₂O+ZnCl₂+Zn(H₂PO₂)₂ ternary systems have simple eutectic type in 298, 333K. One invariant point, two invariant curves and two crystallization region have been observed in the phase diagrams at 298, 333K. Otherwise, One invariant point, three invariant curves and two crystallization region have been observed in the phase diagrams in 313K. In the crystallization regions; (i) Zn(H₂PO₂).H₂ and ZnCl₂, (ii) Zn(H₂PO₂)₂, Zn(H₂PO₂).H₂O and ZnCl₂, (iii) Zn(H₂PO₂)₂ and ZnCl₂ salts have been observed at 298 K, 313K, and 333 K, respectively. In H₂O+ZnCl₂+Zn(H₂PO₂)₂ ternary system, the increasing salting-out effect of Zn(H₂PO₂)₂ on ZnCl₂ with temperature.
