测定的七种三嗪环桥联的双冠醚氯仿溶液对苦味酸碱金属盐(钾、铷)水溶液的萃取平衡常数表明,在三嗪环上带有脂溶性较大的取代基的双冠醚具有较高的萃取能力。还报道了两个新双冠醚的合成。
The equilibrium constants for the extraction of the picric acid alkali metal (potassium, rubidium) aqueous solution by the seven triazine ring bridged bis-crown ether chloroform solutions showed that the double crown with the fat-soluble substituents on the triazine ring Ether has a high extraction capacity. The synthesis of two new double crown ethers was also reported.
