在丙酮溶液中以碳酸铯为催化剂, 以硫代杯[8]芳烃(thiacalix[8]arene, TC8A)和N,N-二乙基-2-氯乙酰胺为底物, 对TC8A的下缘进行修饰合成了一种新的TC8A衍生物——硫代杯[8]芳烃二乙基乙酰胺[TC8A-CH2CON(CH2CH3)2].对含有9种金属离子的汽车尾气净化催化剂溶液进行萃取研究表明, 在pH为3.0的萃取液中TC8A对其中的钯离子具有最高的选择性萃取能力, 萃取率可达99.3%, TC8A-CH2CON(CH2CH3)2对其中的锆离子具有最高的选择性识别能力, 萃取率可达96.7%.

A new derivative matter amidothiacalix[8]arene [TC8A-CH2CON(CH2CH3)2] has been synthesized by modified the lower rims of p-tert-butylthiacalix[8]arene (TC8A) in acetone by using p-tert- butylthiacalix[8]arene and α-chloro-N,N-diethyl-acetamide as substrate, and cesium carbonate as catalyst. The metal extraction properties of TC8A and amidothiacalix[8]arene from automotive catalyst residue solution containing platinum-group metal (PGM) cations have been investigated. TC8A shows the highest extractability for Pd cation which is ca. 99.3%, and TC8A-CH2CON(CH2CH3)2 shows the highest extrac-tion capability for Zr cation which is ca. 96.7% in pH 3.0 PGM solution.

Key words: calix[n]arene, thiacalix[n]arene, synthesis, extraction, metal ion
