The solubility properties of zinc sulfate-threonine-water system at 25 ℃ and the full range of concentration were studied by semi-micro phase equilibria method. The phase diagram of the system and the refractive index of saturated solution were plotted. There was no new compound in the system In the water - acetone mixed solvent, we have synthesized a ternary Zn (Thr) SO4 · H2O solid compound which has not been reported in the literature and its chemical composition, elemental analysis, IR, XRD, XPS and TG- And the thermal stability of the complex were studied.The standard combustion energy (- 11848.76 ± 17.76) J · g-1 of the complex was determined by the precision rotational calorimeter, and its standard enthalpy of combustion (-335.482 ± 5) was obtained. 3 0) kJ · mol-1, and the standard enthalpy of formation (-2.5 6.3 ± 5.769) kJ · mol-1.
