Ⅰ.本文报告了7种西佛碱型双冠醚和经过还原得到的3种仲胺型双冠醚化合物的合成。用两种仲胺型双冠醚制备了聚苯乙烯支载的双冠醚化合物。以所得新型双冠醚作为PVC膜离子选择电极的中性载体,制备了钾离子选择电极,研究了电极性能,测定了冠醚和碱金属离子的络合反应热力学量,络合萃取量。通过碘代反应测定了聚苯乙烯支载的双冠醚的相转移催化活性。
Ⅰ. The synthesis of seven kinds of Schiff base double crown ethers and three kinds of secondary amine double crown ethers obtained through reduction were reported in this paper. Polystyrene-supported bis-crown ether compounds were prepared using two secondary amine-type bis-crown ethers. The new double-crown ether was used as a neutral carrier for PVC membrane ion-selective electrode. The potassium ion-selective electrode was prepared. The performance of the electrode was studied. The complexation thermodynamics and complex extraction amount of crown ether and alkali metal ion were measured. The phase transfer catalysis activity of polystyrene-supported bis-crown ethers was determined by iodination.
