摘要：

Lithium ion forms complexes with crown ethers in a basic, room temperature molten salt. The stability constants of several of these complexes have been determined by lithium-7 NMR measurements. The binary molten salt mixture was 55/45 mole % in 1-methyl-3-ethylimidazolium chloride to aluminum(III) chloride. Stability constants for 1:1 complexes with lithium ion were found to increase in the order 18-crown-6 < 12-crown-4 < benzo-15-crown-5 < 15-crown-5 in this molten salt at 22-degrees-C. This is the same sequence for lithium ion - crown ether complex stability as was found previously in a 55/45 mole % N-butylpyridinium chloride to aluminum(III) chloride molten salt.
