研究了25，26，27，28-四（乙酰甲氧基）-5，11，17，23-四（1，1，3，3-四甲基丁基）杯[4]芳烃（1）在氯仿中从硝酸溶液中萃取银和钯的行为。化合物1能够从约1摩尔dm-3的硝酸溶液中相对于钯高选择性地萃取银，并且有效地从大量过量的钯中除去痕量的银。根据1H-NMR谱的化学位移确定了银离子在1上的配位位置。
The solvent extraction of silver (I) and palladium (II) ions with 25,26,27,28-tetrakis(acetomethoxy)-5,11,17,23-tetrakis(1,1,3,3-tetramethylbutyl)calix[4]arene (1) in chloroform from nitric acid solution was investigated. The compound 1 was capable of highly selectively extracting silver over palladium from about 1 mol dm−3 nitric acid solution and was effective in removing trace amounts of silver from a large excess of palladium. The coordination site of silver ion on 1 was also determined from the chemical shift in the 1H-NMR spectra.
