由于王冠化合物冠硫醚的结构中含有软硷硫原子,因此选择它来配合作为软酸的过渡金属离子以分离或分析这些金属离子.过去,以冠硫醚为配体与铂系金属的配合作用的报道很少,我们为此进行了冠硫醚的合成,但发现它们难以用常法分离纯化,因而采用了高效液相色谱法(HPLG)分离.用HPLC法分离冠醚化合物的研究报道很少,近年来仅见Bij等对二苯并18-冠-6和二苯并24-冠-8在C_8和C_(18)烷基键合固定相及硅胶上,用水-甲醇等作移动
Due to the soft sulfur atom contained in the structure of the crown compound, the crown compound has been selected as the transition metal ion for the soft acid to separate or analyze these metal ions. In the past, the combination of the crown sulfide as a ligand and the platinum group metal However, we reported the synthesis of crown thioethers for this purpose, but we found that they were difficult to separate and purify by conventional methods and were separated by high performance liquid chromatography (HPLG) .Recent studies on the separation of crown ether compounds by HPLC In recent years, only Bij et al. Have observed that dibenzo-18-crown-6 and dibenzo-24-crown-8 are immobilized on C 8 and C 18 alkyl-
