稀土离子与冠醚特殊的络合性能,使它在金属元素分离,萃取及有机催化等方面均有广泛的应用。与稀土硝酸盐络合的冠醚有15-冠-5,18-冠-6和21-冠-7等。但迄今尚未见到有与稀土硝酸盐络合的12-冠-4方面的报道。
Rare earth ion and crown ether special complex properties, it has a wide range of applications in the separation of metal elements, extraction and organic catalysis. Corona ether complexed with rare earth nitrate 15-crown-5,18-crown-6 and 21-crown-7 and so on. However, no reports of 12-crown-4 complexed with rare earth nitrate have so far been reported.
