摘要
本研究测定了2-乙基己基膦酸单2-乙基己基酯(HEH/EHP)与镧系元素镧、铈、镨、钕、钐、铕、钬、铒、镱、镥的1H、(13)C、(31)P核磁共振谱。对HEH/EHP的碳骨架进行了详细归属,并根据(31)PNMR谱峰的积分面积,推测了萃合物可能的配位络合比,(HEH/EHP与Ln(Ⅲ)之比)。对铕、镱、镥为6,对铒为5,对钬、钐为4。
This paper describes our initial effors in the use of NMR techuique for the study of the solution structure of HEH/EHP complexes with lanthanides. We investigate the coordination number of the complex and propose the possible reaction mechanism in CDCL_3 solution.
