利用盐酸羟胺与杯[4]芳烃二醛衍生物的亲核加成反应,设计并合成了下沿含醛肟基团的新型杯[4]芳烃衍生物,经1HNMR、MS和元素分析等表征确证其结构,测定了醛肟基杯[4]芳烃衍生物对系列金属阳离子的液液两相萃取性能,实验结果表明醛肟基杯[4]芳烃衍生物对软酸类金属阳离子具有较好的配位性能,特别是对Hg2+和Ag+的萃取率分别达到39.2%和35.6%。
A new calix [4] arene derivative containing aldoxime groups was designed and synthesized by the nucleophilic addition of hydroxylamine hydrochloride and calix [4] arene dialdehyde derivatives. The product was characterized by 1HNMR, MS and elemental analysis The structure of the aldimino-calix [4] arene derivatives was determined and the liquid-liquid two-phase extraction performance of aldoxime calix [4] arene derivatives on the series of metal cations was determined. The experimental results show that the aldoxime calix [4] arene derivatives have better performance on the acid metal cations The coordination properties of Hg2 + and Ag + were 39.2% and 35.6%, respectively.
