(1) Several bi- and tridentate ligands had been prepared, and in addition to the monodentate ligand, tri-n-octylphosphine oxide (TOPO), they were applied to the synergistic extraction of alkaline earth metals and lanthanide metals. Bis (diphenylphosphinyl) methane (BDPPM) was found to be the most powerful adduct forming ligand. The compositions of the extracted species were confirmed by a graphical method. The extraction constants were calculated on the basis of the composition of the extracted species and elucidated in terms of the molecular structure.(2) Novel 4-acyl-5-pyrazolones having the crown ether moiety as the intramolecular synergist have been synthesized and the solvent extraction of various metal ions are examined. It is expected that the crown ether moiety could behave as the intramolecular synergist and that the selectivity could be governed by the acylpyrazolone and the crown ether parts. These ligands are powerful and selective extracting reagents for alkali, alkaline earth and divalent transition metal ions, and the selectivity is quite unique depending on the intramolecular synergist.

（1）已经制备了几种双齿配体，除了单次配体三辛基膦氧化物（TOPO）外，还将它们应用于碱接地金属和灯笼金属的协同提取。发现BIS（二苯基磷酸）甲烷（BDPPM）是形成最强大的加合物。通过图形方法证实了提取物种的组成。根据提取物种的组成来计算提取常数，并根据分子结构阐明。（2）已合成具有冠状醚部分的新型4-酰基-5-吡唑酮，作为分子内的协同作用，并检查了各种金属离子的溶液提取。可以预期，冠状部分可以表现为分子内协同作用，并且选择性可以由酰基吡唑酮和牙冠醚部分控制。这些配体具有强大的选择性提取试剂，用于碱，碱土和二价过渡金属离子，根据分子内协同作用，选择性非常独特。
