| Abstract: | Zn(gly)2·H2O was prepared by one-step solid-state reaction at room temperature,with zinc chloride and glycine as raw materials.The optimum technological conditions were found as follows:grinding time 80 min,NaOH aqueous solution 0.4 mL,molar ratio of the ligand to metal 2.5∶1.The chelate ratio of the product is 94.39%.The product is characterized by IR,TG-DTA,XRD.The result shows that the constituent of the product is Zn(gly)2·H2O. |
