摘　　要：利用有机溶剂沉淀分离法,以L-赖氨酸盐酸盐和金属盐酸盐为原料,通过氨水调节体系pH值合成了高纯度的赖氨酸铜、赖氨酸锌螯合物;以螯合率为指标考察了合成工艺的主要影响因素,确定了最佳原料配比,pH值及反应温度和时间;并通过化学分析、红外光谱、紫外光谱及热重等一系列分析手段对其进行了表征,确定了赖氨酸金属螯合物的合成。The high pure chelate of copper L-lysinate and zinc L-lysinate chelate compound were synthesized by organic solvent with L-lysine monohydrochloride, cupric chloride and zinc chloride as raw materials in water medium. The synthetic conditions were investigated according to the molar ratio of materials, pH value, reaction temperature and time. In the mean time, the properties of the complex were characterized by a series of analysis methods, such as chemical analysis, infrared spectrum, ultraviolet spectrum and thermogravimetric analysis.
