    Ternary SLE Measurements for the Systems H2O+ZnCl2+Zn(H2PO2)2 at T=(298, 313 and 333) K
    (Chem Soc Pakistan, 2022) Demirci, Sevilay; Adiguzel, Vedat; Sahin, Omer; Erge, Hasan
    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)center dot H2O and ZnCl2, (ii) Zn(H2PO2)(2), Zn(H2PO2)center dot 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.

    The Solubilities and Physicochemical Properties of NaH2PO2-NaCl-H2O, NaH2PO2-Zn(H2PO2)2-H2O, and NaCI Zn(H2PO2)2-H2O Ternary Systems and in NaH2PO2-NaCl-Zn(H2PO2)2-H2O Quaternary System at 298.15 K
    (Amer Chemical Soc, 2016) Demirci, Sevilay; Adiguzel, Vedat; Sahin, Omer
    The physicochemical properties and solubilities of NaH2PO2-Zn(H2PO2)(2)-H2O, NaH2PO2-NaCl-H2O, and NaCl-Zn(H2PO2)(2)-H2O ternary systems and in NaH2PO2-NaCl-Zn(H2PO2)(2)-H2O quaternary system at 298.15 K were investigated-via the isothermal method. Invariant point compositions represent the quaternary system were characterized as the following: 10.65% mass NaCl, 32.51% mass NaH2PO2, 6.50% mass Zn(H2PO2)(2) and 50.34% mass H2O. In solid phases, the salts of Zn(H2PO2)(2)center dot H2O, NaCl and NaH2PO2 center dot H2O were recognized. The crystallization area of the salts were obtained as (i) 79.04% Zn(H2PO2)(2), (ii) 18.62% NaCl and (iii) 2.34% NaH2PO2. Being the least soluble salt, Zn(H2PO2)(2) has the largest crystallization area when compared with other salts present in the medium. According to the results, the crystallization area of was the largest in comparison with those of other salts and at the same time it was the least soluble salt.
