  • Patent number: 5328626
    Abstract: N-ethyl alkanohydroxamic acids, where said alkyl group is a straight chain alkyl group of 8 to 10 carbon atoms, or a branched alkyl group of 8 to 18 carbon atoms, provided said alkyl group is not cyclic, useful as metal chelants for use in organic solvent extractant solutions such as kerosene to extract metals from aqueous solutions by forming complexes of the extracted metal with the N-ethyl hydroxamic acid. Metals can be stripped from complexes of N-ethyl hydroxamic acids at higher concentrations into lower strength acid stripping agents. The N-ethyl hydroxamic acid-containing organic solvent extraction solutions exhibit rapid phase separation from aqueous solutions, good hydrolytic stability and resistance to forming emulsions.
