| 摘 要： | Chirai sodium zincophosphate nanocrystalline has been prepared and characterized. The standard molar enthaipy of the following reaction 12Na3PO4·12H2O（s）＋ 12ZnSO4·7H2O（s）= Na12（Zn12P12O48）·12H2O（s）＋ 12Na2SO4（s）＋216H2O（1） was determined by solution reaction calorimetric at 298.15 K, and calculated to be 33.666±0.195 kl/mol. From the results and other auxiliary quantities, the standard enthalpy of formation for sodium zincophosphate nanocrystalline was derived to be △fHm^⊙ Na12（Zn12P12O48）·12H2O（s）, 298.15 K] =- 24268.494 ± 0.815 kJ/mol.

| Abstract: | Chiral sodium zincophosphate nanocrystalline has been prepared and characterized. The standard molar enthalpy of the following reaction 12Na3PO4·12H2O(s)+12ZnSO4·7H2O(s)=Na12(Zn12P12O48)·12H2O(s)+12Na2SO4(s)+216H2O(l) was determined by solution reaction calorimetric at 298.15 K, and calculated to be 33.666±0.195 kJ/mol. From the results and other auxiliary quantities, the standard enthalpy of formation for sodium zincophosphate nanocrystalline was derived to be Δ fH?m Na12(Zn12P12O48)·12H2O(s), 298.15 K]=?24268.494±0.815 kJ/mol. |
