摘要
按缩合反应合成了一类端基为羧基的Ｓｃｈｉｆｆ碱型开链冠醚其中，Ｘ＝ＣＨ２ＣＨ２－时，Ｒ＝ＣＯ２Ｈ（Ｈ２Ｌ１）；－ＯＣＨ２ＣＯ２Ｈ（Ｈ２Ｌ３）；－ＯＣＨ２ＣＯ２Ｃ２Ｈ５（Ｌ８）：Ｘ＝时．Ｒ＝ＣＯ２Ｈ（Ｈ２Ｌ２）：－ＯＣＨ２ＣＯ２Ｈ（Ｈ２Ｌ４）测定了配体Ｈ２Ｌ１和Ｈ２Ｌ３的酸的离解常数．
Some Schiff base-acyclic crown ethers with carboxyls as their end groups are synthesized by means of condensation reaction,where X =-CH2CH2-,R=CH2CH2-, R = CO2H( H2L1); -OCH2C02H(H2L3);-OCH2C02C2H5(L8) ;X=, R = CO2H(H2L2);-OCH2C02H9H2L4). The acid dissociation constants of the ligands H2 L1 and H2L3 are measured.
