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%.
In the acetone solution with cesium carbonate as catalyst, the lower edge of TC8A was treated with thiacalix [8] arene, TC8A and N, N-diethyl-2-chloroacetamide A novel TC8A derivative, thio-calix [8] arene diethylacetamide [TC8A-CH2CON (CH2CH3) 2] was synthesized and characterized by means of extraction of a catalyst solution for automobile exhaust gas containing 9 kinds of metal ions The results show that TC8A has the highest selectivity for palladium ions in the extract with pH 3.0 and the extraction rate is up to 99.3%. TC8A-CH2CON (CH2CH3) 2 has the highest selectivity for zirconium ions , Extraction rate of up to 96.7%.
