The extraction of cerium(III) and praseodymium(III) from hydrochloric acid solution has been investigated using monooctyl α-anilinobenzylphosphonate (MOABP) and monooctyl α-(2-carboxyanilino)benzylphosphonate (MOCABP). Chloroform, benzene, carbon tetrachloride and cyclohexane were used as solvents and their influence on the metal extraction and complex formation is discussed. The number of the MOABP
研究了使用单辛基α-苯胺基苄基膦酸酯(MOABP)和单辛基α-(2-羧基苯胺基)苄基膦酸酯(MOCABP)从盐酸溶液中萃取铈(III)和(III)。以氯仿,苯,四氯化碳和环己烷为溶剂,讨论了它们对金属萃取和络合物形成的影响。在这两种金属的提取物协调MOABP分子的数目的顺序氯仿降低3 ≥苯≥的CCl 4 ≥环己烷。金属配合物的组成已从提取数据中推导出来,并通过对分离出的化合物的分析加以证实。红外光谱已经研究了配体与金属配位的位置。
