摘要
由2.6-二羟甲基酚(对位分别有甲基、甲氧基、氯原子取代)与单苯并冠醚和二苯并冠醚在强酸催化下缩聚。合成九种新酚醛型冠醚聚合物,并对合成条件,聚合物溶胀性、热稳定性、结合性能和富集分离效率进行了研究,所合成冠醚聚合物动态富集容量为0.15～0.2mmol/g,可用于多种金属离子的吸附分离。
Three series of polymeric crown ethers have been synthesized by the condensation of 2.6-dihydroxymethyl-4-methoxylphenol (or methyl, chloro substitured) with aromatic crown ethers in the presence of H_2SO_4as catalyst. The complexing capacity, collecting capacity for metallic ions and the thermostability of them have also been investigated. The results of experiments indicated that all of the polymers can be used below 185℃ and the colleting efficient for Ag^+、K^+、Cu^(2+)come close to 100% in 10^(-6)～10^(-4)mmol/ml.
