摘要： 由水杨醛与α,ω-二溴代烷或二(对-甲苯磺酸)三甘醇酯反应,制成相应的二醛化合物。再与4′-氨基苯并-15-冠-5反应生成5种Schiff碱型双冠醚,经LiAlH4还原可生成5种仲胺型双冠醚。电导率测量结果表明可与KCl(Rb)盐生成2:1(冠醚单元:金属离子)的夹心型配合物。而与钠离子形成1:1配合物。用双冠醚制成PVC膜钾离子选择电极,并测量了电极的线性范围和选择系数。

关键词: 双冠醚, Schiff碱, 电导法, 离子选择电极

Abstract: Reaction of 2-HOC6H4CHO with X-R-X [R=- CH2CH2-, - (CH2)3-, - (CH2)4-, -(CH2)6-, -CH2CH2(OCH2CH2)2-, X=Br, p-CH3C6H4SO3-] in the presence of K2CO3 in DMF gave 2-OHC-C6H4-OROC6H4CHO-2, which were condensed with 4'-aminobenzo-15-crown-5 to give five new schiff base type bis-crown ethers. Reduction of these schiff bases with LiAlH4 gave secondary amine type bis-crown ethers. Results of conductivity measurement showed that these bis-crown ethers formed 2 : 1 (crown ether : metal ion) sandwich type complexes with potassium, rubidium chlorides or formed 1 : 1 complexes with sodium ion. In addition, the bis-crown ethers were used as an active substance in PVC membrane potassium ion selective electrodes, and the liner range, selective coefficient were also measured.

Key words: Bis-crown ethers, Schiff base, Conductiometry, Ion selective electrode
