摘要
2,6-双溴甲基-4-甲基(或氯)-苯甲醚(Ⅴ或Ⅵ)与双(邻羟基苯氧基)-乙醚(Ⅶ)或双(邻羟基苯氧基)-丙烷(Ⅷ)缩合得到含中心功能基冠醚化合物(Ⅰ～Ⅳ)。研究了它们在30℃下于 CH_2Cl_2-H_2O 体系中对碱金属苦味酸盐的萃取率,实验结果表明,化合物(Ⅰ)与 K^+的络合作用,以及化合物(Ⅲ)对 Li^+的络合作用,分别比化合物(Ⅱ)和(Ⅳ)要好。
This paper deals with synthesis of four new crown ethers containing central functional group(Ⅰ-Ⅳ)and complexation with alkali metal ions. Condensation of 2,6-bis(bromomethyl)-4-methyl(or chloro)-anisole(Ⅴ or Ⅵ) with bis(o-hydroxy-phenoxy)-ethyl ether (Ⅶ) or bis(o-hydroxy-phenoxy)- propane (Ⅷ)gave crown ether compounds containing central functional group (Ⅰ-Ⅳ). The percentage extraction of compounds(Ⅰ-Ⅳ)for alkali metal picrate in CH_2CL_2-H_2O system at 30℃ were investigated.Experimental results showed that complexation of compound(Ⅰ) with K and compound(Ⅲ) with Li more than compound (Ⅱ) and (Ⅳ) respectively.
