摘要：

A novel resorcinol-based, 25-crown-8 compound with an intraannular oxyacetic acid group and a pendent, lipophilic phosphonic acid monoethyl ester function has been synthesized. Competitive solvent extractions of alkali-metal, alkaline-earth, and mixed alkali-metal and alkaline-earth cations from aqueous solutions into chloroform by this lipophilic lariat ether with two different proton-ionizable groups were investigated. The lipophilic diionizable lariat ether exhibits markedly different efficiencies in the extraction of alkali-metal cations and of alkaline-earth cations from basic aqueous solutions.
