含卤素杯4芳烃衍生物的合成及其对金属离子的萃取性能

摘要

以对叔丁基苯酚为原料,经逐步反应在对叔丁基杯[4]芳烃的下缘引入含卤素的基团,得到了一系列含卤素的杯[4]芳烃衍生物(记为1,2,3,4)；利用核磁共振谱和气相色谱-质谱证实了目标产物的结构；并评价了产物对水中的Cr3+、Cu2+、Ag+的萃取性能.结果表明:杯[4]芳烃衍生物2、3和4分别对Cr3+、Cu2+和Ag+具有较好的萃取效果.%Several calix[4] arene derivatives (denoted as 1, 2, 3, and 4) were synthesized from p-tert-butylphenol through a series of reactions by which halogen atoms were introduced onto the bottom edge of the target products. The structure of the target products were confirmed by nuclear magnetic resonance spectroscopy and gas chromatograph-mass spectrometry. Moreover, their extraction capacity for Cr3+, Cu2+ and Ag+ in water was evaluated. It has been found that as-synthesized calix[4] arenes 2, 3 and 4 show excellent extraction performance towards Cr3+ , Cu2+ and Ag+ , respectively.
