✦ Synopsis

ethyl]trialkylammonium salts 1 were synthesized from the corresponding oxo compounds and hydroxylamine in the presence of Ni 2+ ions which stabilize the oximes by chelation. Salts 1 are surfactants possessing a powerful chelating suhunit. Their ability to extract different metal ions from aqueous solutions into organic solvents was tested by metal ion transport through a liquid membrane.
