摘　　要：以甘氨酸和金属锰盐为主要原料,制备甘氨酸锰络合物,探讨反应温度、反应时间、反应体系pH值等因素对甘氨酸锰产率的影响,确定最佳合成工艺,并通过红外光谱表征产物结构.实验结果显示,制备甘氨酸锰的最佳反应条件为反应温度70℃,反应时间2.5h,反应体系pH5 ～6,在最佳条件下制备的甘氨酸锰络合物的产率为47.86％;红外光谱证明产物为甘氨酸锰络合物.The manganese glycine complex was prepared by glycine and manganese salts. The influences of the reaction temperature, reaction time, reaction system pH on product yield were discussed, and the structure of product was characterized by FT-IR. The result shows that the optimum reaction conditions of manganese glycine complex were as follows： reaction system pH was 5 to 6, the reaction time was 2.5 h and the reaction tempera- ture was 70 ℃. The product yield of manganese glycine complex was 47.86%. FT-IR confirmed that the prod- uct was manganese glycine complex.
