ABSTRACT:
Dioxime extractants having the following general formula: ##STR1## where R and R' may be any of a variety of organic hydrocarbon radicals such as aliphatic, alkyl and aryl radicals. R and R' may also be hydrogen. Preferably R is an unsaturated hydrocarbon or branch chain alkyl group containing from about 3 to 20 carbon atoms and R' is hydrogen or an unsaturated hydrocarbon or branch chain alkyl group containing from about 1 to 10 carbon atoms. Preferably, there is a difference of about 3 to 10 carbon atoms between R and R' resulting in dissymmetry of the resulting dioxime molecule. Preferably, the dioximes also contain a total of about 5 to 32 carbon atoms. Representative compounds are methyl octyl dioxime and methyl hexyl dioxime.
Organic preparations containing such dioximes are useful for the extraction of copper, nickel and cobalt metal values from acid or basic aqueous solution.
