| 摘 要： | 用2,6-二羟甲基-4-苯基苯酚分别与二苯并-18-冠-6(2B18C6)、二苯并-24-冠-8(2B24C8)、二苯并-30冠-10(2B30C10)、苯并-15-冠-5(B15C5)、苯并-18-冠-6(B18C6)缩聚合成了五种酚醛型冠醚共聚物。我们用聚冠醚的氯仿溶液萃取苦味酸碱金属盐水溶液,研究了它们对金属离子的络合性能。结果表明,聚冠醚(PB15C5)和(PB18C6)的萃取能力和选择性显著优于相应的单冠醚。

| Abstract: | Five new poly-co-condensale of pheaolic and crown ethers were prepared by the condensation of 2,6-dihydroxymethyl-4-phenylphenol with dibenzo-18-crown-6(B18C6), dibenzo-24-crown-8(2B24C8), dibenzo-30-crown-10(2B30C10), benzo-15-crown-5(B15C5), benzo-18-crown-6(B18C6) respectively and cationbinding abilities were evaluated by extraction of poly-co-con-densates solution in chloroform from aqueous alkali metal picrates solution. The results indicate that the extractability and cation-selectivity of polyco-condensates (PB15C5) and (PB18C6) are more effective than the corresponding monobenzo or dibenzo-crown ethers. |
