摘要: 本文研究了以1-苯基-3-甲基-4-4-三氟乙酰基吡唑啉酮-5(HPMTFP)与1,10菲罗啉(Phen)。三辛基氧磷(TOPO)、三苯基氧磷(Ph3PO)、三丁基磷酸酯(TBP)和二戊基亚砜(DASO)的氯仿溶液对CO(Ⅱ)的协同萃取.协萃图上发现,HPMTFP与Phen协萃效应显著,与TOPO、Ph3PO协萃效应较小,而与TBP、DASO基本上无协萃效应.本文由协萃图数据斜率分析和求协萃反应平衡常数的方法,推断萃合物组成为Co(PMTFP)2·B(B分别为Phen、TOPO、Ph3PO),求得的各协萃反应的平衡常数如下: 
根据模拟萃合物Co(PMTFP)2·2C2H5OH和萃合物Co(PMTFP)2·Phen的单晶X-射线结构研究结果,讨论了萃合物的结构和产生协萃效应的原因。 |

Abstract: The synergistic extraction of Co(Ⅱ ) with l-phcnyl-3-mcthy1-4-trifluoroacctyl-pyrazolonc-5(HPMTFP) and some neutral donors, viz triphcnylphosphinc oxide (Ph3PO),trioctylphosphinc oxide(TOPO), 1,10-phcnanthrolinc(Phen), tributylphosphatc (TBP) and diamylsulphoxidc (DASO) has been studied in chloroform solution with acetate media Co(Ⅱ) is synergistically extracted as Co (PMTFP)2-B, where B stands for different neutral donors The extraction reactions arc as follows:  The influence factors for the syncrpistic extractions were discussed according to rcsult of sture tural studies of the extracted complexes as well. |
