Abstract:

        Cerium(Ⅲ)complex was synthesized in water solution by reaction of cerium pro to chloride with cyclohexane carboxylic acid (C6H11COOH)as ligand and using ammonia to adjust its pH value to 5.5.The complex was characterized by thermog ravimetric analysis, element analysis and IR spectra .The results of TG and element analysis show that the formula of the cerium (Ⅲ)complex is Ce(C7H11O2)3.The IR spectrum o f the prepared complex suggests that the coordination of cerium (Ⅲ)complex is chelating .The influence of different post treatment technics on the purity of complex was discussed .And then a better post treatment technics  was obtained.The product obtained is respectively w ashed with hot water and hot alcohol thrice during the process of filtration .After that , the product is dried in vacuum at 120 ℃ for 3 hours.Finally , the pure cerium (Ⅲ)complex with cyclohexane carboxylic acidis obtained.

摘要：         以环己基甲酸(C6H11COOH)为配体, 用氨水调节其水溶液的pH 值到5.5, 与氯化亚铈水溶液反应,合成了环己基甲酸铈(Ⅲ)配合物。通过热重、元素分析和红外光谱对所制得的环己基甲酸铈(Ⅲ)配合物的组成进行了表征。热重和元素分析的结果表明, 铈(Ⅲ)配合物的化学式为Ce(C7H11O2)3;红外光谱的分析结果表明, 环己基甲酸铈(Ⅲ)配合物的配位方式可能为螯合配位。讨论了不同的后处理工艺对环己基甲酸铈(Ⅲ)配合物纯度的影响, 从而得到了较佳的后处理工艺:反应所得的产物在抽滤过程中, 经过热水洗涤3 次、热乙醇洗涤3 次后, 在真空120 ℃下烘干3 h, 最终可得到纯净的环己基甲酸铈(Ⅲ)配合物。
