Abstract
Lipophilic crown ethers with pendant proton-ionizable groups are novel metal complexing agents for use in solvent extraction of alkali metal cations. A variety of dibenzocrown ether carboxylic acids and dibenzo crown phosphonic acid monoesters have been examined to probe the effe ct of structural variation within the complexing agent upon selectivit y and efficiency in solvent extraction. Results from competitive solve nt extractions of alkali metal cations from aqueous solutions into chl oroform are summarized.
