摘要	Current research found that the extraction process of lithium ions by crown ether-ionic liquid system was a cation exchange process inwhich lithiumions are dehydrated. Obtained and predicted the structure of the composite product of crown ether and organolithium, and based on the weighing method, the formation of 1:1 complex [Li(B15C5)](+) was determined. and it was found that the extraction of lithium ion by the diluent was in accordance with the cavity effect of anion. The coextraction of diluent and ionic liquid, the percentage of competition of common metal cations in aqueous solution to the extraction of lithium ions by Benzo-15-crown 5-Ether (B15C5) were also discussed. Finally, the effect of different diluents on lithium isotope separation and the thermodynamics of lithium isotope exchange in the B15C5-[HMIm][NTf2]-anisole system were studied. The separation factor of lithium isotope was the largest when chloroform was used as the diluent (alpha = 1.034), and the exchange of lithium isotopes was a spontaneous reaction at low temperature (Delta H < 0, Delta S < 0).
