摘要
利用斜率法、饱和萃取法和电导滴定法确定了标题双冠醚和钾离子、钠离子的络合比分别为2∶1和1∶1(以冠醚单元计),并通过紫外—可见光谱研究了此双冠醚对苦味酸钾、苦味酸钠的络合性能,以及在不同极性溶剂中此双冠醚对苦味酸钾、苦味酸钠的萃取率。
The determining methods of slop analysis, satiety extraction and conductance titration were used, and the result indicated that the title ligand forms 2∶2 (crown unit: metal ion) complex with K + and 1∶1 complex with Na +. The extraction behavior was studied by UV-Vis spectra. The extraction yield of title ligand in various polar media was determined.
